Im glad you are out of the situation. My boyfriend also used cocaine, but he has never become violent with me, or at anytime ever that Im aware of. You did the right thing by not going back there. His mind is all messed up from the drugs, and he is not able to control himself. I was talking with another member, and she was telling me about her experience with cocaine psychosis. It can happen sometimes with use, especially if mixed with other things. You should do a search on that, very scary.
Now, if you add on this fat, chubby thing he has going on, what is the attraction? LOL
