I have kids with my ex boyfriend and we just went to court for child support. He keeps telling my kids that I'm sleeping around, when I'm not. He tells them that I'm happy when they are with him because I get to go out with all my lovers. Then my daughter keep crying to me and I keep telling them no and assuring them. Its just overwhelming because I have no proof, so how do I go by making him stop. I just want him to stop telling them lies. They are always crying to me and I just don't know how to put a stop to his madness.
