Liz, being sweet is part of the whole passive aggressive playbook. He needs to keep you off balance and by being nice he is doing that.
Keep the focus on you, it doesn't matter what he is doing now. He had plenty of chances, years and years, to make these changes before you decided to move out and he didn't.
It was only important when HIS lifestyle was being impacted. As far as I can tell, nothing's changed.
Your friend,
