Recently, my spouse keeps the phone turned off all the time. They hardly respond to my messages, and even when they’re next to me, they constantly reach into their pocket. When I ask them, ‘Why are you doing this?’ they reply, ‘I find it annoying.’ I’m really confused; I don’t understand what kind of situation this is. I’m especially worried, thinking maybe they are looking for something distressing.
It happened to me; my ex would constantly hang up the phone. Turns out, she was doing it to avoid talking to someone else. I hope that’s not the case for you, but be open and communicate.
You say he even puts it in his pocket when he’s with you, it feels like the phone is blocking you from seeing him. So, did you ever know his password before, or did you notice anything that he was hiding from you?
@makarnaoncesi I used to know the password, but they changed it recently. I asked a few times why they keep it closed, and they give excuses.
@uykuarasi not everything may be betrayal, don’t jump to conclusions. Maybe there’s work stress or something, people sometimes look for an escape. There’s no need for paranoia every single time 
This issue generally stems from a lack of communication. You might try to understand their discomfort with keeping the phone off, but also express the insecurity you feel. It could be a closed communication problem 
In the title, you mentioned ‘my spouse keeps their phone off’, but there is more suspicion in the content. If you clarify the connection between the two, people will provide better interpretations.
I think the problem is serious.
The issue of feeling disturbed is nonsense. In my opinion, there’s a 90% chance that something is off. Why would a married person hide their phone? We’re tired of excuses.
@cokdaseyapma you’re jumping to conclusions right away, we don’t know the guy’s confusion. Maybe it wasn’t like this before, maybe it’s just a temporary thing.
Keeping the phone off is one thing, changing the password is another. When these two come together, it attracts some attention. If they really weren’t hiding anything, they would have just sat down and said it openly. Has any of the excuses you’ve mentioned so far been convincing?
So when does this phone stay off? Is it constantly or at certain times? For instance, is it like this when you’re at work or when you get home? A bit more detail is important.
If it’s not constant but closed at certain times, I would recommend examining those times closely. Is it always the same time zone, the same days? If there’s a pattern, it’s easier to form a clearer opinion about the reason.
