My waking nightmare

[Lorelai]

This morning H had a proposal: I move out of our house and he moves back in and I take a cheap apartment somewhere nearby which he'll pay for. Is it possible this could help him see how difficult the situation is and how hard it is to have the kids 80 percent of the time (though I don't think I could stay away as much as he does. I mean, he doesn't even call in between the days he's here and he rarely spends a full day with them, usually no more than a few hours.)
During this talk I did ask about reconciliation as an alternative we have not explored. He said he's much happier not being around me and that his blood pressure has gone down! He said, "I don't want to be on blood pressure medication just because of my marriage!" But isn't it possible, H, (I didn't say this but wanted to) that your blood pressure has gone down b/c you're not a full-time parent of two small children anymore? I'm not trying to sound sarcastic.
What should I do? My DB plan at this point is to completely detach. Being around and talking to H makes me absolutely crazy. It's hard to completely detach though because we have the children. I love my babies dearly but if H and I didn't have kids together I would not want this stranger of a man he's become anywhere NEAR me!
