FLTC, I don't think Michelle would be apologizing for the things she did to better herself...more for not noticing that he felt neglected or lonely. Also because things may have been swept under the rug with the thought of we can deal with this when school is over (I totally get that by the way) or things are less stressful.
I also think this would be more for Michelle to get some things off her chest rather than trying to get a reaction out of her H. I know that it helped me to detach and try to move on. There were just some things I needed to say and I don't think I would have let it go until I did.
