He's feeling sorry for himself and self-righteous. Asshole!
My WH always seems to feel like somehow the kids are supposed to make him feel loved and validated. Ummm hello...A) they are kids, you are supposed to just show them love and not expect something back and B) they are't stupid! they see through that self-serving act faster than adults, I think.
Spending big $ and expecting that to fix it. And then blaming the kids when it doesn't. Sheesh. Narcissist much?
