Maybe its just me but I see a lot of positives in your post. Your H is in MLC without a doubt. He seems to have a lot of confusion. He needs space. You going dark is a great idea. Your H needs to digest all of this and see positive changes in you. You have a chance to rebuild in the future. You need to be strong up until that point.
Him giving you a hug is huge. He is in there some place. You need to let him do his work. You are making huge strides to get better. You need to keep moving forward.
