Only thing you can do right now is let it run its course. People in MLC will usually rebuff any help or suggestions describing what a MLC is, especially from their spouses.
You just have to keep up a certain level of detachment so that with each positive step he takes, you take with a grain of salt. Continue to live YOUR life for yourself. And as hard as it is, try not to hold onto every word and action your H does. It's going to leave you being the confused one.
That's why they call this a roller coaster. Your H is on an emotional one. But it is your choice to stay on it or be dragged along with him.
Patience and prayer are what's going to help you get through all this.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
