my fiancee (she) have been together for 4 years and a half, we’re planning to marry each other in 2022 and we’re moving in our newly bought house this month. We’re used to use each other’s phone to look for things if for example mine or hers is charging and we need to quickly look something up, or chat with some mutual friend.
A couple of weeks ago she started being really possessive about her phone, not allowing me to use it, hiding notifications, not taking up calls while with me or hiding the screen with her body while seemingly typing stuff. She also changed her unlock code, she started setting it in “do not disturb” mode when she usually always had her sounds on.
When I tried to confront her about all of this she just told me that I’m paranoid, that nothing has changed from before and that I’m imagining things. She said she changed the code and hid notifications because someone saw her unlock code at work, and she usually leaves the phone on her table, and she doesnt want someone to saw her notifications.
I don’t know what to think, the change in behaviour was so sudden that I’m sure something is happening. Is it cheating? Is she in “danger” at work? Is something happening to her that she’s scared of? Please help me
