My BF and I have been back 2-gether for 2 years; we were high school sweethearts, but things are totally different now than what they were before. He don't trust me and I never ever cheated on him or lied to him about anything. Just can't confided to him about something's. Because he gets mad and starts calling me names or something to the sort. Well he left me about a week ago and I suspected him to call me and he did. But it's always the same thing: It'll be different this time, I won't drink as much or I'll trust you. I want a trusting, lasting relationship, and stable environment.Anyways he started calling again and he wants to talk but his talks always lead to the same thing. So my question is: Should I talk to him, let him come back, or should he get help with his anger, personality disorders, and get on his meds? What should I do? I am getting very angry with him and fed up with his stupid games

I sounds to me like you need a new boyfriend.
Can you not talk to him and have him accept it - or will you need the police? Hopefully he'll listen.
His drinking and his paranoia and his leaving... are a DISASTER.

Get moving... This isn't High-School anymore. He's headed nowhere and you're not getting any younger. There's more to life than being a back-up plan for a drunk.

Right?

Hope you can do it.

Why would you love someone who doesn't even trust you and gets mad easily?

I think to love someone you need A LOT OF REASONS. You can wait and choose, you know?

Be rational now, leave this controlling insecure loser!

OK, you've painted the "perfect picture" of a person who has little if any trust in others BECAUSE: "he isn't trustworthy." This is a classic example of a person so entrenched in deceit that other's are perceived as coauthors of this deceit. We can be a product of what we practice and that can change how we see the world around us. Next time he's in your face tell him he sounds like he feels guilty about something and that it shows every time he opens his pie hole. Then let him know you don't have time for "flakes" or "creepazoids." Good luck, you'll do fine.
