I am really uncomfortable with his. The way I see it, you seem *very* insecure. She is not doing anything with them, they are friends.

Is she not allowed to have any friends then? Or at least no male friends at all? What if your girlfriend had a lesbian friend. Would you demand that your girlfriend stop speaking to that friend too?

This seems very controlling and frankly, speaks more about your insecurities than anything wrong that she was/is doing. Actually, you are the one doing something 'wrong' by going through her phone (invasion of privacy?!)

It is not healthy to want to keep a partner in a cocoon because you seem to have trust issues. I would focus on that and explore where this insecurity stems from, rather than try to change my partner and tell them who they are allowed to see or talk to!
