I think if I had behaved as horribly as my xh has, I would not think I had the right to a relationship - I would see the need to make amends. This total failure to see this, and to (now) apologise endlessly for trivial stuff as a sort of proxy for the main thing is weird, and dislocated.

He has morphed from a wonderful man into a strange person, and got stuck there. I think that a part of him doesn't like this, but he isn't willing to address the real problems

Dealing with him just does my head in. I try periodically, but you cannot deal with a MLCer. The ground shifts all the time, and they have to be right, and you have to be wrong if you express another opinion. Then you find them doing what you suggested, but in a warped way so they can say 'I did what you said' What i want is some authenticity, not a semi compliant grumpy teenager
