Mandy, you are going to have to learn something that has taken me awhile to learn. You have no control over what he does. I am in a similar situation in the sense that my XW left me with 2 little kids and has nothing whatsoever to do with them. I know it makes you mad as hell, but really there isn't anything you can do about it. He will pay for what he has done down the road, but in the meantime, you have to salvage what you can, explain to your son this wasn;t his fault and make the most of things. I know this isn't very comforting to you, but unfortunately it is the way it is.
