I have been with my boyfriend on and off for three years. Our biggest problem has been his ex girlfriends, one of whom i believe he cheated on me with, if not physically then emotionally. We broke up for about four months, and during that time he began sleeping with this exl. He came back to me and told me he missed me, and that he wanted to try things again. For several months he has been an angel, and even promised to stop having contact with the ex. However, we travel in the same group of friends, and have to see her often. She is very angry at me, and continually badmouths me, gives me dirty looks, and takes vindictive actions against me. He continues to be friendly toward her, and they are talking again a little bit. I believe that she is angry at me because he let her think that I "stole" him from her. I tried contacting her and trying to make peace, but it ended badly. I believe he should confront her and ask her to leave me alone, because I have done nothing to her. Is this too much to ask? Is it too much to ask for him to stop seeing her completely? I am so tired of this. I am trying so hard to rebuild trust, but it is so difficult with her always up in my face. Also, some of the actions she has taken against me, he knew about and didn't tell me about until months later. I feel that he should "have my back", and that being friendly to her is just not right. Am I wrong?
