"I stopped asking to see my kids because she won't let me see them"? Yeah, ok. If roles were reversed, and you were not crazy (which you are not), is this the response you would have if he tried to prevent you from seeing your kids?
Didn't think so. I mean, COME ON. That says a lot about him. And he's posting that publicly? "I just gave up on my kids because my big bad mean W isn't being nice to me"? LAME.
Don't let his crazy become your crazy. You can't really rationalize with his irrationality.
