Here's the problem: You should never have to put restrictions on a relationship. If you don't trust her, you shouldn't be with her. I still don't think it's okay for her to be communicating with someone she has romantic history with. She should respect the fact that it makes you uncomfortable...and either introduce you to him, or stop talking to him. Like I said, restrictions shouldn't be forced. You're trying to control her...and that's why she's getting mad at you. You're scared she's going to leave you, which is why you're trying to control the situation. If you don't trust her, let it go. If she can't respect your feelings and try to compromise, let it go.
