I've been thinkin about ya while I was away from the board this past week.
To borrow some words from my now deceased grandma, it "gripes my fanny" that your H is still blaming you for his failures, namely not making the break from OW. It makes me mad that he puts this off on you with the lines like "you had this won" or calling your changes "fake."
You are a saint for putting up with him and I'd like to slap him for not getting the fact that you can only do so much without reciprocity on his part.
Any chance that you could go for counseling in another town?
Keep the faith. I don't know what it will finally take to open his eyes, all I know is that he has to do it for himself.
