Thank you ((thine)) for your post and you ask some important questions. Yes he treats the girls well and they love each other. We're very civil in front of the chidren and even privately except for occasional disagreements.

I agree the best gift for kids are happy parents. Unfortunately he's made it clear, he doesn't want to live apart and would make it ugly..which would be bad for the kids. I have to pick the least harmful situation and I think it's the one I'm doing ATM..for now at least.
