I got bored and read his Facebook messages. I found out he was talking to other girls on Facebook during the first few months we dated, being very flirtatious and such.

You just went through his messages without any ulterior motives? Why would you invade his privacy like that? Or were you actually looking for something?

This was the first time I suggested breaking up. After that, everything he did seemed like he had an ulterior motive. We settled the problem and I forgave him (but I never forgot).

I don't know if he loves me or not, but he's very convincing when he says he does. T

He really wants me to trust him and I'm trying but I've exhausted myself.

Have you ever had a talk with your bf about your expectations and your feelings? Does he know that he fucked up and that you're still very upset? Has he ever apologised and what does he do to improve his relationship with you? Is he trying to regain your trust or is he just "expecting" to have it again? What could he actually do to regain your trust? Is it even possible?

Do I give him that chance? Whenever he has an interaction with either his best girl friend, I get very anxious and angry. Like I want him to stop right now, but I can't stop him from talking to his best friend. What do I do?

I think you aren't a great match since there are many incompatibilities and you lack good communication skills. This relationship doesn't do you any good and it's a piece of work. Have you thought of seeing a therapist about your anxiety?

Regarding your bf's best friend, of course you can tell him that you feel uncomfortable about her. Have you ever done that explicitly? Have you explained to him WHY you aren't a fan of her? How has he reacted?

But he really wants to make this work. What do I do?

It doesn't need two people for a break up. If you want out, you can do that even if he doesn't agree. I mean you already decided a long time ago that you wanted to break up and start a new chapter in your life. Don't let him hold you back.....
