T.,
First let me say that I am sorry you are going through this. I think one of the things that we all agree on is that we never want our children to hurt. I went through a divorce a few years back and know how much I worried about my children. Although I don't know how to address you directly on how to get him to stop bad mouthing you, I can tell you that you are doing the right thing in not saying anything about him. There are many many studies that show that as the children grow, they realize the truth anyway. Lean on your strength and faith and instead of focusing your energies on how to stop him, try to focus your energies on building the trust between you and your boys. They are young and you are their mommy. They will love you regardless. Foster your relationship(s) with them both individually and as a family. Let them know that nobody loves them like you do and they can ALWAYS talk to mom. You are in a rough time and you will need time to be with your friends and just to be alone, but I caution you to not let that need take away from them right now.
You will be fine. I am living proof....
