Think back the days when you just started DBing. You feelings were extremely hurt. Yet, you were able to DB. You can still do it now. I try to remind myself that. I feel so exhausted sometimes and just want to say "forget it". But then I try to think of the timeline and can see little/big steps that H made and I know it is working, though as a zig zag line rather than a straight line.
Your H needs to hit bottom first before he can come back. He needs to move out. personally, I won't push him out but I really don't know what is the "correct" action to take. He needs to miss you.
I hope the new ic will help. It's actually good that he is reaching out to someone to get another opinion. good luck on that.
