i went through almost the same thing with my son's father, had to get a restraining order, i was so scared he would try to break the deal, but i ended up moving and havn't seen him in over 20 years. i still am scared because he was so abusive but he ended up staying away anyway. there is hope he will have to stay away with the restraining order if he doesn't want to get into any more trouble. Just saying that there is hope
