Been through this. The only asnwer is to get out. He uses fear to control you. My ex husband stalked me, threatened my life, and the life of others. Finally had enough, told him I was going underground, and we would see who will kill who. Needless to say the next time he saw me was on a street in the area, and he put pedal to the metal getting away from me. In his mind, he had no idea what I was going to do. That was a wake up call for him to stop the madness and move on down the road. Its all about control, your boyfriend's issues are his, the next female he encounters will have the same problem. The dangerous thing is to let abusers take total control, when that happens, they will take your life. However if you take control, leave him, get protection from the authorities and male members of your family and be ready to defend yourself if you have to, he will have no choice but to leave you alone.
