Actually, I found my way out of the morass came from thinking much as Lighter and Ann3 have said here. My problem was that I was putting so much time and energy into anger and blame, I wasn't making positive progress in directions I wanted to go. Not that it wasn't justified, just that his actions and choices should be his problem, and they'd become my problem, and I wanted to be free of it. So I thanked the universe that I wasn't crippled in the way he was, accepted that he is very very flawed, and perhaps--I never got to "absolutely," but perhaps, he did the best he could at the time. He didn't care because he had no capacity for caring. I told myself it was like he was colorblind--how do you describe red to someone who has never seen it? He didn't fulfill his responsibilities. He didn't love his children or his wife; indeed he abused them quite badly. What made it happen? Not sure. Something. If he wants help with that, he can confide in me. Actually, I'd be interested to hear it. But he won't, because he doesn't have the courage. And I think he knows it.
