Well i just found out that she still has a nickname with heart emoji on him in her contacts since they dated. It's really stupid detail, but it's details like these that make me overthink. Thanks for your advice though!

yes i get what you are trying to say. From what I know about her she has experience with men trying to get something from her. And also, it happened few times when we were in bars/clubs that when some men approached her and made a move on her she froze and wasn't able to do anything about it. I'm not blaming her for anything because she has been through some traumatic stuff and that's why she freezes up. But that makes me even more worried, what if he makes a move and out of fear or something she won't be able to defend herself? I know I'm probably just overthinking, probably I'm just overprotective. idk

I mean i did admit that the issue is in me, what I'm asking for is advice about how to communicate it without her feeling like i want to put restrictions on her
