Maybe he can't deal with confict? Maybe is knows he's wrong but can't admit it and is presenting something else on the surface? If he is wrong, it sounds like he must have some sort of guilt attached to it. Maybe he can't live with the guilt and he knows he's selfimploding.
He can't deal with almost anything. Even good things sometimes. I think there's a 3 ring circus going on in his head most of the time, and he's always reacting to something he's obsessing about instead of what's actually happening.
