Sorry for your situation. But I don't think your son should have to be in the middle of this. The child support will run out before you know it, and then the ex will either get bit by karma or find someone else to manipulate. It stinks that you son is probably not getting any of the benefit of the child support, but it sounds like he is a hard worker and maybe has learned some good life lessons. Best if luck to you.
