I wonder why he was so defensive about the "I's"...since you were just retelling the story of what happened prior to your D's scratches, and H wasn't there. Do NOT feed into the "this is why I am leaving", I hear that now and I completely ignore it. Its ridiculous!
Also, instead of the 100 sorries you gave him, you can say "I am sorry you feel that way." and leave it at that. Walk away (or just remain silent in the car until you reach your destination).
He is setting you up for failure, but you (and me!) allow it to happen. He doesn't hate you, he hates himself and that's too hard for him to look at. I am sorry you are so down, really I am. I have been there (go there every day lol), but you are allowing him to get to you. Don't!
