BD, I find I want to throw the towl in each time I act positively with WH. Must be because I have to wait till I am feeling 'up' in order to do that. When I feel 'down', I regret having extended the arm of peace/civility/whatever you want to call it.
Mt WH has not lifted a finger to help me during the pregnancy, birth or raising of this baby. He left me for OW. So unlike your H, mine is a total "swine" in the partner and father stakes! In fact, I think he is behaving more poorly than Newmamas, your and Gatsby's husbands put together!
Fullmoon, I still have those reasons you hint at for keeping it civil. I often wonder just how much this is preventing me from cutting him off properly and as he deserves - emotionally and legally/finacially.
Red, your H is probably up there in the 'head completely up his a$$ stakes' as mine. Cruel, selfish, chaos kids. The cake-eating just eats away at the LBS, I agree. Unless you completely remove yourself (e.g. no contact). I will see how I go and perhaps tell him not to contact me if I can't handle things.
