My ex has primary custody of our teenage son. Her behavior has always been erratic but has become much worse since I have become involved in a relationship. She continues to say derogatory things about me to my son, including telling him that I don't love him. He and I have a pretty good relationship. Because of this, he tells me when she says these things. She has recently remarried. Although I don't feel he has issues with his mom's new husband, he recently expressed to me that he can no longer tolerate living with his mother. The reason's he gives are the fact that he feels she has issues with her anger and they argue on a daily basis. My insticts are to go back to court and seek primary custody immediately. Before I do this, I want to know if I have a chance in gaining custody. I don't want to put him through the hell that will be his life with her if I don't have a chance.
