Amen to all that's been said.. this is his problem. Me thinks Mr. Sue is having a tantrum. Where did I read someone say (might have been lwb!) to respond to these tantrums like you would your child. Allow him to have it, take responsibility for it and clean up after he's done. He waits until 2 weeks before the move to bring this crap up? He's definately deluded!!
You are wonderful, strong, and are not gonna let him drag you down, right? Hold your head up, and keep on trucking.
This isn't to say that some day your H might change and really wanna try and then it will be up to you to decide whether you want that. This isn't the time though.. and he's not there yet. There's a big difference between selfish hanging on and a genuine attempt to fix the M and reconcile. He's being very selfish.. if he were ready to work on the M, it would look more like concern for you and his daughter.. blame would be the furthest thing from his mind. When J finally turned around it looked more like this - "I love you - I can't live without you, and I'll do WHATEVER it takes to make it right - Please, please forgive me.... etc"
