Bf problems..

I'm really sorry that you're in a tight spot, but I honestly think you should let him go. If he has broken a promise that serious, then you should put your heart on guard against him. Also, doing drugs makes guys do bad things to their partners sometimes. He can get high one day and end up beating you. Would you really like to sacrifice your self-respect just to stay with someone who is obviously less than you deserve? Take some time away from him and see if he'll change. If he doesn't, then I advise you to just stay away from him for your emotional and physical safety. I hope this helped you out! I'm sorry you have to go through something like this, though :(

break up with him, this is not the kind of guy you want in your life. you could as a friend suggest he get into a program to help him get clean but that is all i would do. he sounds like bad news and more trouble then a six month realationship is worth.

Drug addictions are horrible, and they are agonizing to get over, both psychologically and physically. If he is truly trying, you must understand that it is extremely difficult. If he is really trying, he may need your support. You should try to help him if you can, support him, and understand that this process is agonizing for him, as I am sure it is for you as well. If he isn't trying at all, maybe you should talk about it, and if he still does not understand, perhaps you should not be in a relationship with him. But if he really is trying, then you should stay with him and support him all you can through this long, difficult process. Good luck to you.

It depends.
It's hard to stop doing drugs, and you should help him. If you don't, he might start beating you. Then it'd be a good idea to break up.
But if you want to stay with him, I suggest you support him and help him get over his addiction.

I know it will be hard, but I think you have to let him go. My teacher once brought up a good point. You're on a high chair (the role model) he's on the ground. Now it's going to be easier for him to drag you down, then for you to pull him up. If you don't let him go, he'll probably drag you into it, whether you believe it or not. Hope this helped :)
