I asked my partner for a loan because I need to get by until I receive my salary from my new job. To be honest, I told them I would pay it back, but their expression changed, and I sensed some coldness. Okay, they accepted, but it felt like they were thinking about something else. Was it really something to make such a big deal out of? Do you think issues like this can cool down a relationship?
I think this is very normal. My ex and I used to support each other a lot during a certain period. I was unemployed, and she had lent me money. But in the end, there should be trust in a relationship; you already said you would pay it back. Maybe she felt strange because she was thinking more emotionally than logically?
Maybe you explained the topic a bit too casually, that’s why the guy hesitated. Because people see money as a serious matter. You said, “I will pay it back,” but did you specify a date or anything? Without clarity, some people can get anxious.
Financial situations can be sensitive in relationships. Psychologically, financial support can be perceived by the other party as a responsibility or a burden. Especially if you haven’t received a salary yet, they may also have anxiety about “what if they don’t pay me back.” It is particularly beneficial to have discussed budget planning.
I’d like to add one more thing: we were actually talking about a clear amount. My friends have helped me with these kinds of issues before, so I didn’t understand why my partner got so tense when I asked. It feels like there’s something else going on 
I was wondering, did you say something like “we’ll talk about the refund issue when things are clearer,” or did you directly say, “I’ll give it by this date”? Those are separate statements. Maybe your lack of a definite plan made them wonder.
