My parents are divorced and they don;t get along. My mother is planning to move away and she supposedly has a "friend" who is going to come get her, but she said if he does that he will also kill my father. She talks online all the time to her internet friends about how abusive my father was to her and us, but it's all lies. My mother was the abusive one. She abused me, my siblings, and my father. But she tells all these people that he was abusive and then she gives them her home address, my sister's home address (where my son and I are living), my brother's home address, and my grandmother's home address (where my father is living) and then they discuss killing my father. All of this is done on her computer and I've never seen it, but she has told my sister all about it. I believe that my mother really will try and kill my father because she's tried before. I don't know what to do about this. My sister doesn't want to say anything because she just wants our mother to leave and I don't know if I can because I've never seen or heard any of it myself.
