He says he wants the D for sure!

Also, cfronk, give some consideration to how big of a factor that the "blame game" might be in some of your "circular" interactions together. I'm almost seeing that there might be a lot of "cause-hunting", and "attack/defend" positions happening between the two of you. Maybe not a lot of them on your part, but it looks like it's happening just the same.

Give some thought to more ways you might be able to short-circuit this pattern, to de-emphasis what's going wrong, and place more weight onto what things are going right.

Remembering, also, that actions speak louder than words.

Hang in there, my dear. A lot has happened lately, but I think you're dealing with it very well! I'm still not convinced that he's really ready for things to be over between the two of you. I see him as wanting things to be "fixed", but he's just not sure how to do it. That's where all the hard work you're doing might be able to help lead him in the right direction.
