dzd, I'm in an almost-identical situation, but there's no OP in mine. Right after the bomb, my H & I were re-connecting and having better and more frequent sex than we'd had in years. H said just because we enjoyed each other, had good sex, shared the same sense of humor, etc, it didn't mean he had the "right feelings" he needed in order to stay in our M. So he withdrew everything--no more sex, no more affection, no more dates.
H is still trying to get it together to actually move out and it's very stressful. He refused to participate in MC. It's extremely confusing. The way I see it, being good friends with benefits is EXACTLY what one should want/expect of a long-term M with kids--but these foolish spouses of ours fixate on some feeling that's missing, yet refuse to do anything to rekindle that romance.
What does your W think of her actions in terms of the effect on your kids?
