I feel for you my ex is a saint compared to yours. I started paying support as soon as I moved out don't know if that was the right thing to do or not. Do you have a lawyer if so what does he say. I don't any faith in lawyers. its all formality. mine did nothing for me he thought he did wonderful with the visitation he got me, but that was never the problem my ex loves when I have them. I know this is hard for you but some day your son with figure out what your ex is doing and he will resent her for it. Have you ever checked the website ANCPR. You can purchase information about divorce and your legal rights. Its full of information including domestic violence issues. good luck
