The recent currency increase affected the rent, my roommate doesn't understand

It could be this as well: Perhaps they are underestimating the impact of the currency increase, meaning there has been a price hike, but they might be thinking "how much difference will it make anyway?" Sit down, calculate the expenses of the last 6 months, and show them the expenses that will arise due to the increase. Sometimes the issue arises not from confusion, but from a difference in seriousness.

Perhaps they don't take the rise in currency as a personal issue, meaning that even if they accept the idea that it "affects rent" in a straightforward way, they might be expecting you to take the initiative regarding the increase in shared expenses. Has there been such a division of responsibilities before? Or have you always been the one to handle the "calculations"?

If you always handle the accounting, maybe there's a certain comfort in thinking, "you'll figure it out anyway"? But then it's worth considering how aware you are of your responsibility. For instance, is moving easy, or is sitting down to pay the bills easier? Are you really sure you've thought this decision through?

Have you linked this currency increase issue to your roommate with a clear example? For instance, did you show a straightforward calculation like, "with this rate, the rent increases by this much, and your share would be this much"? Maybe they don't fully grasp the situation with exact figures and are just muddling it in their head.

Maybe the issue isn't the clarity of the numbers, but rather viewing the currency increase as something abstract. In other words, they might feel that the increased rent isn't directly related to the rise in foreign currency. By the way, have you talked to them to see if they think the rent hike is exclusive to their house, or if they have noticed the overall market too? Many people are missing the local context now.

It seems to me that my roommate here has the mindset of "the currency increase is just a story, there's another reason for the rent hike." It’s kind of like saying "Sezen's songs are not just love songs." No, my friend, there’s a concrete increase at play. You'd better just line up everything from the grocery receipt to the rent invoice in front of them and say, "here's the soundtrack of the currency." Maybe they’ll get it.

Well, have you tried explaining the issue not through currency increase but in the simplest terms like "the rent has increased this much, we now need to pay this much"? Because for some people, currency, economy, and such can seem abstract and distant. Focusing on concrete payments and budget might bring more clarity.

It's not that they don't understand, but if they don't want to? Maybe the issue is a conscious state of "not understanding" rather than sharing the rent, to pay less. Have they always had such habits from the beginning, or did it start recently?

Maybe they're looking for a more local explanation like "our neighbor reduced their rent by 100 lira, while ours is increasing" instead of a big reason like the currency hike? People are generally influenced not by the big picture but by comparisons around them. How are the other rents in your area, have you talked about this at all?

Maybe the roommate is approaching the rent increase based on the landlord's individual whims rather than external factors. In other words, they might be questioning, "Why is our landlord doing this?" instead of thinking, "It's okay if everyone is increasing their rents." Can you communicate the landlord's currency-related justification directly? That would make it more binding for them.

It's a housemate, not a landlord. This increase doesn't provide any gain for them. Maybe they're thinking something like "why are we accepting this?"—wondering if there's something the tenants should do. Have you tried playing the "we'll just move somewhere else" card directly?

Your roommate might be hesitant to accept this increase without comparing the market by asking, "Could we find something better if we moved now?" Have you tried sitting down together to research the general situation of rents and how prices are doing elsewhere? In other words, is it an increase or are we still at an advantage with the current situation? Let's clarify this.

If there is so much hesitation about this increase, have you thought about opening an account based on "who pays what will feel comfortable" instead of an equal payment model? Because some people are questioning not the increase, but the burden that falls on them. Look, if you say, "this amount will reflect on you," maybe then they will stop and think.

Could your roommate be more focused on how to manage this raise rather than the raise itself? I mean, it's not just about the exchange rate; they might be thinking, "What is the best solution in this situation?" Have you tried asking directly, "What do you suggest?" and putting the ball in their court?

Your roommate might not be able to face a significant change in their budget instead of questioning the rent increase. How about suggesting to review their expenses and share? Would creating a clear picture by asking, "Where would it be hard to cut back?" help find a solution?

Maybe the issue is not entirely about trust? You say the increase is reasonable, but they're still not convinced; perhaps they're questioning how long the landlord can sustain this increase. There might be a concern like, "If we accept it once, will it become a constant?" After all, landlords who see a wave of rent increases sometimes lose control of the situation. Have you thought about this?

Everyone has approached this very solution-oriented, but maybe your roommate just doesn’t want to be convinced about the raise; it's that simple. Sometimes the issue isn’t a logical explanation, but just getting angry just because there’s a raise. Could it be that the more you argue and drag it out, the more stubborn they become? That's another angle to consider.

Maybe it's time to stop discussing the issue of rent and just ask directly, "Do you want to keep living in this house?" Because if there is dissatisfaction or a desire to move independent of the rent, then that's a completely different matter. They might seem to be talking about currency but are actually discussing the home.

Instead of a "who will pay how much?" issue in your roommate's attitude, it could also be a matter of "who will take on how much risk?" As you know, moving or starting a search for a new place in the face of a rent increase is not an equal risk for both parties. Have you tried discussing which details, like the time it takes to find a place, the deposit, and moving costs, place more burden on whom?

Could your roommate see this increase as part of a larger system and be blowing up the next rent hikes or general economic imbalances in their head? In other words, if the issue isn't the current rent but rather the fear of "what comes next?", you might need to discuss long-term plans together instead of just the increases. Do they have such a concern?

Is your roommate concerned that when the rent increases, other expenses might also rise at the same rate? Like, "If we pay this rent, what will tomorrow's grocery or bills be?" Maybe the issue isn't just the rent, but being condemned to a living standard they can't manage overall. Check in with them.

Could it be that your roommate's resistance is related not to the amount of the increase, but to the timing of the increase? For example, does he currently have another financial burden, making this increase extra troubling? They might be stuck on the question of "why now?" rather than simply accepting the raise. It's worth looking into that.

It seems like your roommate is just making excuses instead of proposing a solution. If you had stopped talking about price increases and suggested a new arrangement in the budget, what would they say? For example, did you clarify things by asking, "If we move, what will we find for cheaper?"

Is the currency issue an excuse or is it real? First, look into that. Because if the source of the increase is currency and it's thought of as a fixed expense, the likelihood of further price increases will be high. If your roommate still pretends not to understand the situation, they either really don't get it or they have some other interest. "How far and on what basis will prices be raised?" Put this on the table openly, because you're circling around a lot.

If your roommate can't reconcile the rent with the currency increase, is that a lack of information or a logical conflict? Because if you stop talking about currency and start calculating the profit/loss of concrete things like "moving costs, relocation expenses, time loss," maybe the situation becomes clearer. Even if the impact of the currency is debatable, it would be hard to ignore if moving ends up being more expensive overall. Approach it from that angle.

Forget about exchange rates and all that, is it a principled stance against raising the rent directly? Because discussing "why an increase is necessary" is one thing, but showing resistance like "rent increases shouldn't happen" is another. Can you separate the two?

Maybe the issue isn't the rent, but your friendship dynamic. You know, one person is always playing the martyr role while the other has become accustomed to being comfortable? Sometimes, when we talk about the budget, it turns into a debate about "who's trying harder" rather than the actual expenses. Especially if you've been roommates for a long time, old issues may have been piling up underneath. Have you tried discussing them?

We keep saying it's about the price increases, it's about foreign currency, but the real question is this: Did you discuss a system for rent increases beforehand? Was there an agreement like a certain percentage or a certain date? Or are you currently proceeding completely improvised? If there was no prior agreement, everyone will justify their own position as they see fit.

Even if the housemate doesn't understand foreign currency, comparing rent increases with the prices of other houses around is still a method. Did you check the rents in other places together? If there wasn't a comparison like "Ours is still good" or "There can't be anything better here," just discussing currency might be futile. Has the local market become a concrete argument in your hands?

Could your roommate's situation be more about "not wanting to accept" rather than "not understanding"? Because for some people, the issue is not just about money, but a resistance to the change in the routine they’re used to. For instance, aside from the rent increase, did they have similar resistance regarding any other issue? There might be something to explore from there.

To understand how much the currency is affecting the rent increase, how about chatting with the other tenants in the apartment or nearby? If someone in the same building is paying less for an apartment with similar features to yours, then the currency argument weakens. Or, if everyone's rent increases are similar, then your roommate's refusal would be an unnecessary resistance.

If the landlord is using foreign currency as an excuse, ask for proof. Are they paying off debts with the rent in foreign currency or buying materials? Because everyone mentions "foreign currency" whenever it suits them. Your roommate could be right too; if it seemed like a baseless excuse, they might not trust it.

The landlord might be using foreign currency as an excuse or not, but there is something important here: After the first increase, typically the second and third wave increases follow. Is your roommate resisting out of fear of "if we accept it now, when will it stop?" Because some people get anxious that if they give in once, it will always go up. Have you talked about this?

Did your roommate talk directly to the landlord when you requested a raise? Sometimes, in such situations, direct communication can reduce people's doubts or resistance. A face-to-face conversation with the landlord can make a serious difference; have you tried it?

Or could it be something like this: Is it really not because the rent seems exorbitant, but because your roommate knows that an increase in rent will result in cutting back on their own expenses, and they don't want to make that cut? Like maybe the currency issue, "I don’t understand," and so on is just a defense. Have they shared their own expenses in detail with you?

No one has asked, but this could also be the case: Your roommate might actually want to move out from here and is perhaps trying to bring up the issue under the pretext of the rent increase. Could their extensive discussion about the rent hike be a way to prepare the ground for saying "let's move" without directly saying it? Have they ever hinted at something like that?

Could your roommate be trying to buy some time by postponing the decision about the raise? Maybe they don't want to move but are trying to extend the current situation as long as possible. Have you ever thought about setting a date and talking definitively?

I don't think your roommate has a problem with not understanding directly, but here's the thing: In this raise conversation, isn't the responsibility falling on you? I mean, if you're working harder regarding this increase, has a relaxed sense of security formed for them, like "it'll be resolved anyway"? In such situations, I think the burden should be clearly discussed.

Is your roommate saying "I don't understand" about the connection between the currency and rent, or are they questioning the general rationale behind the increase? Because sometimes people can't accept not the economic details, but the part that asks, "Why has it risen so much?" How much transparent information do you have regarding this increase?

Perhaps the issue is whether this house is still worth it after the price increase. If the question in their mind is something like, can this house or a better one be available for the same price, they may have shifted from a debate about right or wrong to the question of "where are we, what are we doing". Is this house really still worth that amount?

Could it be that your roommate doesn't understand the issue of the raise but hasn't realized the seriousness of the situation? I mean, when they say "I don't understand," is there a kind of comfort in thinking "this isn't my problem"? Because sometimes people don't take action until the consequences of the situation start to affect them.

Maybe the issue is not just the rent but a general dissatisfaction with the house? You know, the increase in expenses might be an excuse, but could it actually be a situation where the comfort of the house, its arrangement, and the dissatisfaction with the living space are the real problems? Has this ever been expressed before?

How willing is your flatmate to forgo their share after this increase? I mean, they can say "I don't understand" and shift the perception elsewhere, but in the end, it's about what comes out of their pocket. Did you directly ask, "How are we going to share this?" It’s important to listen to how much they understand and explain.

If your roommate is saying "I don't understand," maybe it's easier for them to keep their distance from the topic. If they were really looking for a solution, they would sit down and go over the calculations, examining the bills and housing listings as needed. Have they ever made such an effort, or are they just talking about what you bring up?

Maybe the issue isn't "rent," but rather "sharing responsibility." In other words, in this conversation about the time, is the burden of the resolution process on you? If you're constantly doing the math and trying to reach a conclusion, their saying "I don't understand" might have turned into a more comfortable area of less mental effort. Have you ever talked about the distribution of responsibilities?

I think the issue might not be so much about "I don't understand" but rather that you haven't asked, "How does this situation reflect on you?" For example, how will they afford that increase? Is their own budget suitable for it? Maybe they have some anxiety but can't express it. Did you discuss these things very clearly?

The phrase "I don't understand" can sometimes be a more polite way of saying "it doesn't concern me" or "I don't care." Instead of questioning where the currency is tied to the rent, maybe we should inquire why continuing to live in this house after the price increase is in your common interest. Why are you still defending this house, have you said this to them?

Perhaps the question "who feels this increase more" is more important than "why was the raise implemented". For example, he might not be facing a budget deficit. What does this increase mean for you? Perhaps your struggle is invisible to him because he has no burden in his own pocket.

But if the increase in the exchange rate affects the entire rent, this is a shared problem of both people, not just one side. Saying "I don't understand" won't solve the issue. I think you should directly offer, "Shall we sit down and calculate?" in an assertive manner, because as long as they avoid it, discussing the division won't be possible.

They may not understand the connection between interest rates and foreign exchange, but if they're acting as if they're in a completely foreign country regarding foreign exchange matters, is this a choice or a genuine lack of knowledge? I think it’s necessary to figure out where they got lost; for instance, ask them, "Which part don't you understand?" Maybe they are too lazy to make the connections, or perhaps they’re completely unaware of basic concepts.

"I don’t understand," he says, but I think it’s important to see if he has offered any other solutions during this time. For example, has he ever said something like, "Should we move?" or "Is there another way?" Because if he’s not interested in solutions at all, it means he’s completely leaving you on your own.

But is there a chance to negotiate based on the increase rate instead of the foreign currency? In other words, have you thought about directly going to the landlord and asking, "Is this place worth it?" Maybe your roommate can take over this part; we talk about generating solutions, and this could be their responsibility.

It's easy to say "I don't understand" and step aside, but even if we completely disregard the currency, how are we going to share this rent? Even if they don't have budget issues, have they shown any willingness to make adjustments because you do? Have you ever talked about the fact that when prices go up, not everyone is equally affected?

I think you're taking the "I don't understand" part too seriously. I mean, if someone really doesn't understand, they can learn it in 5 minutes on Google; the issue is not understanding, it's that they don't want to. So let's see who pays how much, who earns what, lay it all on the table and let it come to light.

Why does your roommate cling so much to the "I don't understand" part? I mean, if the issue is really that they don't understand, they should be open to learning instead of showing this much resistance. Or is there a passive resistance of "I don't understand because it's convenient for me not to understand" going on here? In that case, just doing math wouldn't be enough, because the problem seems to be more about attitude than numbers.

If your roommate is saying "I don’t understand," maybe you need to explain the seriousness of the situation in the same language. If expenses like currency exchange or rent remain abstract, show how much you’re in the red this month or which expenses you’ve cut back on. Sometimes people don’t empathize until they see the other person struggling.

After all, you can't just make a rent decision as if you're cutting branches by yourself. Check if that person is pretending to understand or if they're subtly washing you over with bleach inside their "I don't understand". Because you can't linger in uncertainty; it's either the bill or the suitcase.

Saying "I don't understand" and withdrawing won't save you on its own, but maybe there's something like this: If your roommate is already reluctant to share the burden of expenses, or if there’s no budget issue, they might have entered the "why should I argue" mode. Have you expressed how serious your need for a solution is? Because as long as it doesn't suit them, this sentence will just hang in the air.

There's rent involved, there's money, there's currency, but in the end, it all comes down to your breaking point. After so many price increases, there's no point in explaining again to someone who says "I don’t understand." Either it's understood or the course needs to change. For example, if house exchange wasn't discussed, ask about that; let's see if they really don't want to understand or if they just have no solutions in mind.

Perhaps beyond just "I don’t understand," they might actually think that the seriousness of the situation doesn’t concern them. It seems like they view it as your problem. Did they ever sit down and ask you about your action plan? For instance, did they say anything like "How will we solve this?" You can derive some intent from that.

You're holding onto it together, and the costs are shared. It might not work for him, but he can't just ride on your back. Just ask directly, "I can't continue like this, what are we going to do?" Let's see if he's coming up with a solution or still playing "I don't understand."

When someone says, "I don't understand," why not ask in detail, "What don't you understand?" For example, what couldn't they calculate, which part doesn't make sense to them? It could also be that there's something you left out while trying to explain. Instead of making assumptions from the start, try pulling the thread of the conversation and see if you can untangle it.

It's highly likely that someone who simply says "I don't understand" prefers to stay away from the real economic picture. But here's the main point: In communal living, everyone must somehow lift their heads and assess the situation. Have you ever come up with a solution, or have you just stuck to the "there's an increase" part? Because if you haven't proposed a new rent or another housing idea, you'll keep going in circles.

I think your current position is unclear. Are you just saying "I’m struggling," or are you directly stating "we need to do this" and proposing a solution? Because if you're voicing a problem without showing results, the other party can remain silent in a way that suits them. Don’t keep the door closed; it leads to a kind of passive agreement.

The qualification of "I don't understand" is important here. Is there really a lack of economic information, or is it simply a defense of a comfort zone? If you say, "I'm explaining the difficulty, I'm providing a solution, and still, they don't understand," perhaps the issue is not entirely misunderstanding, but rather a resistant breakdown in communication. Therefore, ask the question clearly: "How will this burden be shared?" This will clarify the avoidance of the solution.

Have you ever thought about this part: Maybe you need to make a bolder move to show your seriousness? For example, say something clear like "I can't stay in this house with these numbers." Because sometimes "I don't understand" actually means I don't really care. Give it a try and see how much it shakes things up.

"I don't understand" might just be a tactic to stall for time. I mean, you probably know they understand, but they might be delaying you by not taking action. Your thought should be: Even if you find a solution, is this someone who would still drag their feet when it comes to taking action? Perhaps you've experienced similar kinds of delays in other reactions as well, just check.

Maybe they are trying to pass the responsibility by saying "I don't understand." But this situation may be more based on individual culture than a lack of economic awareness. In other words, our shared life culture has generally shaped itself around a "let everyone manage their own affairs" mindset. Now, they may be turning a blind eye to the details that do not suit them. So, do you think this is a personal comfort or a general reflex of 'let someone else solve it for me'?

Before getting to the solution, clarify the most fundamental thing here: Are we really sharing this rent increase, or not? Because if every time he says "I don’t understand," you are covering one part of the expenses, he is already using your gesture. Speak clearly about the accounts, you need to understand how much you are willing to put your hand under the stone. From there, things will take shape more clearly.

Maybe it's just a habit that when someone says "there's an increase," you are automatically expected to balance things out. If you’ve previously taken the initiative and resolved this issue, you might feel stuck in that role. It’s not that they "don’t understand," but perhaps they think "this is their job." I suggest you take a look at your current workload.

Perhaps you have never talked about not just the rent increase, but also overall budget planning. Does saying "I don't understand" come from being completely unfamiliar with the issue? Do you have a clear understanding of how other expenses shape up during the month? Maybe there’s a mindset like "I’m buying these, so it’s fair" in their head. Have you tried laying out all the expenses and discussing "what am I missing here" openly?

Can you leave the numbers abstract for someone who says, "I don't understand"? I mean, how much has the currency increased, how much has the rent risen, how much do you need to share the difference per person—would putting this on paper help? Maybe they need something visual; not everyone can understand through words.

Maybe when he says "I don’t understand," he’s actually questioning all the expense items? For instance, you mention the currency, okay, but was there any alleviation in other expense items? Didn’t you talk about that either? Is everything just rent?

"I don’t understand," they might not be openly rejecting your approach to sharing costs, similar to how you have them, but they aren’t saying it outright. In other words, could they be questioning the very notion of paying such a large amount for the house upfront, rather than the equation of "currency increase equals rent increase"? It may be necessary to discuss your motivation for choosing this house directly.

Maybe he's saying "I don't understand" because he doesn't want anyone to disturb his own routine? You know, there are some people who don't care about things like currency or rent; they have a way of life they're used to and hold tightly to it. Is this friend one of those people? Or is he completely indifferent? That needs to be looked into.

Brother, he says "I don’t understand," but maybe he really can’t manage the cash flow. You know some people are not even aware of what comes in and out of their pockets; they spend whatever comes in and let whatever goes out be empty. The issue in his mind is this: "I’m already paying this much rent, what’s the difference?" If you’re causing the feeling of "you’re already paying too little" instead of providing a detailed explanation, he might retreat accordingly. If it’s not feasible anyway, let’s not prolong the conversation.

Perhaps when they say "I don't understand," they aren't accepting the increase, meaning they might be questioning, "Is this much of an increase normal?" Accepting the raise and sharing it is one thing, but getting stuck on the logic of the increase is another. Have they never spoken to the landlord, or are they arguing with you more?

There's also this: if they're saying "I don't understand," maybe the connection between currency and rent seems too complicated for them. They might want to hear something straightforward: "There was an increase of this much; you have to pay this much more." If they heard the direct impact of currency fluctuations on their pocket rather than some technicalities, would it be clearer? Some people find detailed explanations unnecessary; perhaps it confuses them.

Maybe this person is trying to evade responsibility by saying "I don't understand"? Is there a general state of passive resistance in everything? If it's not just about this topic, it could be a general strategy to avoid expenses. Check where else they say "I don't understand."

"I don’t understand," they might say, but perhaps they are questioning how you divide based on the changing rates? In other words, if the math that you find fair doesn’t make sense to them, are they seeking to calculate their own account with every increase? Did they get stuck on the method of distribution without it being discussed?

The phrase "I don’t understand" feels a bit like a mechanism for postponement. Sure, there are things like currency fluctuations and rent increases, but how was this done before? Were they understanding you until now, and only now they’re starting to not understand? Maybe they’re choosing this way instead of directly saying "I’m against the increase."

If he says "I don't understand," maybe he is suspecting something about the time. Are you sure that the landlord hasn't made an above-normal increase using the excuse of currency fluctuation? Perhaps the other party is concerned about this increase being accepted directly without question.

It seems like a small detail, but that's where the issue actually started. I couldn't feel at ease without clarifying that.

Even if the phrase "I don’t understand" is used as a tactic, there may also be a class conflict underlying the situation. In other words, while the effects of currency fluctuations and rent increases are pressures on your life, for him, this increase may still be an abstract concept. Differences such as income levels, spending priorities, or how prepared one is for the increase may also play a role in his withdrawal. It's not just about calculations; it's necessary to determine whether these differences are being discussed.

Could they really not understand when they say, "I don't understand"? Not everyone has the same level of financial knowledge. Maybe it’s necessary to explain the connection between currency and rent in detail; otherwise, it turns into a completely pointless discussion. How about explaining it step by step from the beginning and then asking again what they said?

Maybe the issue is independent of the currency-rent and related to the budget limit. Even if he understands, if he doesn't have extra money to spare, it might be pushing him towards a defense of not grasping the subject. Have you ever asked, "Can you afford it?"

Perhaps the issue is not "I don’t understand", but rather "I don’t care". I mean, rent increases, currency exchange, and so on, might not occupy a significant place in their life. Do they have another priority that makes them this relaxed, I wonder.

Now, there is something that so many people overlook: Is it really fair for the landlord to justify the rent increase with currency fluctuations? After all, there is no law that says rent increases must follow the currency. Perhaps the issue is fundamentally flawed, and that’s what needs to be addressed. When explaining this to your housemate, why not open the discussion with the question "Did the landlord do the right thing?"

the main issue here is whether "I don’t understand" truly means not understanding, or if it’s just a way to brush off the topic without prolonging it. If it’s a defense mechanism, what’s the underlying reason? For instance, is there confusion about the landlord trust beyond just the rate increase, or about the overall rental arrangement? We need to delve into this trust issue before directly asking "why don’t you want to make the payment?"

"I don't understand," perhaps the issue is not in the rent, but in your dynamics. There may be underlying issues that have accumulated, and if this is just an excuse, it will come to light again. Take a look at what else is not being discussed between you.

Is your roommate currently saying "I don't understand" as an excuse to avoid paying, or do they genuinely not grasp the connection between currency and rent? You can't resolve this without distinguishing between the two. So, leaving "I don't understand" unexplained might allow them to act as if the topic doesn't concern them. Let's be straightforward and say, "What don't you understand?" and see.

Let's assume your roommate really doesn't understand; but does he know how sustainable this rent situation is? I mean, aside from currency fluctuations and price increases, is there any discussion about how much longer you can bear this burden? Maybe the issue isn't that it's not being explained, but rather that he hasn't realized your limits, which is why he's so at ease.

Maybe they are waiting for you to find a solution by saying "I don’t understand." As in, it’s a situation similar to task sharing. Even if they don’t understand the part about "this rent increase is due to the currency exchange," could it be that they are looking for a partnership where an automatic solution is offered in the end? In other words, they prefer your guidance. Consider this perspective a bit.

If your roommate doesn’t understand the currency-rent situation or is pretending not to, I think the main issue right now is whether you have a plan for the consequences of this increase. So let’s say the rent is paid, what will you do when the next increase happens or when another expense comes up? Have you discussed this at all?

If your roommate says "I don't understand," that's fine, but not understanding something like the increase in currency/rent is a bit strange, isn't it? The fact that they can't grasp such a fundamental issue raises another question: Do they really have a general disconnection from life, or is this just a mask they wear when they're bored? If this isn't clearly understood from the start, conversations may end up being pointless.

Okay, but after saying "I don't understand," does he also equally split the bills and grocery expenses with this logic? So, is it just the rent that he doesn't understand? Because with that same mindset, he should also be asking, "Why are these grocery prices increasing?" Shouldn't he?

If he says "I don't understand" and behaves normally with other expenses, he might be picking and choosing what suits him. But there’s also this: Before the rent increase or in your general household arrangement, is there an invisible burden-sharing issue for him, for example? Things that seem equal sometimes aren't, and could he have gone into a "let this one be like this" mode thinking that it was previously unbalanced?

They may not understand the increase in rent, but even if they don't grasp the impact of currency fluctuations, it doesn't make sense to me that they aren't realizing the fact that "rent has increased, we're paying more now." Directly compare the amount you're paying now to what you paid in the past to clarify what has changed. "I don't understand" isn't enough; they need to question and investigate the reasons.

Could what he means by "I don't understand" not be the effect of the currency on rent, but rather the way you are accepting the rent increase? Like when they say, "Why was the increase made directly, we didn't question it, we didn't object"—could it be something like that? Maybe he had another solution in mind, and instead of expressing it, he's leaving it to you with the "I don't understand" tactic. You might have overlooked this.

"I don’t understand," he says, but has he said anything regarding the arguments of the landlord or the real estate agent during the period of the rent increase? Because during the acceptance process of the rent increase, it is essential to understand whether he is troubled by the direct words of the other party rather than your attitude. Maybe it’s not about currency or anything; perhaps he has fixated on a negotiation issue there.
