I think that your H is baiting you. He wants you to fight back and so he works harder and harder to try to get you to break. Once you do, he's happy and he can follow you around and torment you and let you know that you are still on this stupid merry-go-round with him. He doesn't want you to get better. He wants you to be just as miserable as him.
He's going to keep trying harder and harder the better you get. It sucks - I know. Don't let him drag you down. Just try to stay away from him as much as you can. Don't believe anything he says. I can't believe how much credit I gave my H. He has much worse problems than me and I was listening to his opinion about me???? Give me a break.
