Hi!
S & Nathan have given you good advice. I would let it ride for a while. H needs to feel his safety line is there, that doesn't mean he has to use it. Don't give him a reason to. Just back off and keep up dbing. The best thing is that he's home and he's trying. Don't do anything that will make him feel any pressure. If he feels pressure from you in any way, he will perceive it as an attmept to control him, and he will try to prove to you that he is beyond your control, read: he will retreat to his hideaway.

You are in a real good position. Hold it firm and steady, but gently. Good luck.
