I don't know what to say but I am so sorry you have to put up with his crap. He is feeling extremely guilty. I agree with others. He feels that he really f'ed up and does not know how to fix it. The easiest way he knows now is to get a D. My H once told me that leaving me was easier than going with OW. He chose to stay but that's not after moving out first.

I think most of them really need to hit rock bottom first before they turn around. And that "rock bottom" depends on each individual. He does not want a D. He probably just feels that it is easier to start fresh than come back to face you. Too guilty.

Meanwhile, take care of yourself. You deserve a good husband. someone who will respect you and cherish you and will owe up to things. Unfortunately, your H is not at that stage now.

HUGS.
