Sounds positive that he is leaning toward the IC and MC. I hope you are seeing people that are highly behind M, and don't reverse course the first moment someone thinks they want D.
Your H may find multiple reasons to say a D may be better as he second guesses his thoughts and feelings, which you probably see him testing already. He may feel too guilty to fully return. He may fear going back to his old self, or you to yours. You should both be different wiser people now, better people.
Can you see yourself acting "as if" he is not broken and doesn't need fixing? That is different than saying a better restored M will take work from both of you. What if he had only veered off life's track at a fork in the road and is trying to get back on the preferred route? Would that make him broken, or lost, or an easily distracted traveler? He won't want to be judged too often, or deemed broken - even if he admits to having lost his way.
Express your pleasure at his choice of returning to a life with you in it. There will be proper time later for addressing how he hurt you. He won't want to come home to expectations of hearing about it every day he wakes up. That is where I think you can both benefit from help of good counseling. Utilize the safe place to have those talks, with a skilled moderator.
Let him set the pace. If he wants to talk about something around you or at the house, let him lead, with comfortable room to breathe. Be willing to stop the conversation before you get all your answers or share all you pain. It will all happen in time, MLC time.
Good luck, and prayers for strength & patience to both of you.
