You said: "I am getting good at not reacting on impulse and I am taking things as they come for now" and I'm glad to read that. Good for you. That shows tremendous growth on your part and a willingness to change. Not that I've doubted your willingness before, but it is good to see you verbalize it.
His C's statement about H's behavior being what is "comfortable" for him makes sense but does nothing to help your M. Did you express to the C that his "comfort" is killing you and you need him to do something UNCOMFORTABLE and soon? Just wondering.
Also, his regret over the current situation and your lack of trust in him is good to have him express. Getting it out is important if he's ever going to be able to act on it.
Hang in there, my friend. The sun will shine on a dog's ass from time to time, so there is always hope.
