Women's Rhinestone Belts

My mother's boyfriend and I got in a fight just over a year (a fight verbal) and she ended up trying to make me over with his car, my boyfriend and I decided that at this stage, we when done with it and did not lack around our daughter. So we ended up staying at NH NC to be closer to family. It has been more than a year since I saw this woman and she has come to know NH for Easter. Well my friend decided to see it. I was not happy about this but his mother and then, if it wishes to proceed further. But we agreed that it would not come into our house or be near our daughter. She arrived today at 12.30 and my friend leave the house, I got into our room because I was so shocked that he left our house after everything that women do it after us and promised she would not be allowed to enter our house. He went up and I asked him why he left after he promised it would not be in our house and he told me to cope. So what am I supposed to do now. This woman is violent and dangerous. How do I treat it might be back? And what do I do with my boyfriend shares? Thank you for any suggestion, I know it's a crazy situation I need help here.
