Stop answering your phone when they call you. If you don't have Caller ID, get it. They can't make you feel guilty if you aren't letting them. You know the truth. My MIL never understand the truth about her son even up until her death. The only way I could stop the madness from her was to quit talking to her. It was hard at first and I felt mean doing it, but I just stopped taking her calls and then she could no longer mess with my head. Just like you can't control your husband and his behavior you also can not let others control you! Make your own decisions.
