There is nothing worse than...

I know someone that keeps her children away from their father just to be spiteful. In no way is it helping the kids. Also she lies about not relieving child support. Saying the father doesn't pay, just to make him look bad. He wants to be apart of his children's life. Should he fight for custody?? I think that is the worst types of parent. Especially if the father is trying to do right by his kids.
