I didn’t mean to sound prying. I’ve been in a very similar situation, just genders reversed. I tried confronting him and I tried giving him space too. But it didn’t work out anyway, so I’m interested in knowing what other commenters would say and what turns out to be the truth of the matter down the line. It could be that you’re being paranoid and it’s just her temporary phase. But you could be right too. The thing is we can’t say. And the sooner you can internalise that, and continue your days as usual the better. Some people need space and being patient with them is the most beautiful way of showing up for them. Once the exams have passed or before that if you can schedule a conversation with her to reason out and talk openly, it will help. If I were in your place, I’d ask her if she needs some time to herself for the exams (so that you’re not anxious about her unavailability) and look forward to talking things over once the exams are over to work out a middle path for future. I understand things are easier said than done having been able to only partially implement this myself. I think all I needed to hear was - as of now I can’t know for sure what’s going on, let me stop killing myself over it and go on with my day. If you lack in the friends department, you can ping me to chat a little and take your mind off things if I sound sane enough (no I’m not shooting my shot).
