Nope, but he does not pay child support either. I would NEVER give him any money.
I guess I decided I have to pick my battles. I would rather do w/out the child support than to have to engage with him even more so than I do now as we have two minor children together.
I have decided that I will plan to support myself and my kids. Any extra that I ever get from him will just be that, extra. I won't count on him at all for anything, including money.
So far this is working. Luckily I have a decent job and a low house payment so I can support us at this point w/out any $ from him.
