I find my self in the same situation as you, except my H ad an EA (I tink so, but he doesn't). I have found that NOT talking about our M when we're together puts him in a better mood. Give H all the space he needs and in the meantime, do things you enjoy. When he sees you don't need him to be happy, it'll make him think. That's going to be my course of action. Everytime he criticizes me, instead of getting mad like I used to, I now ignore his comments and walk away. No arguments. Leaves him thinking.
Married 20 years 2 teenagers H in midst of MLC Physically together, but emotionally distant for 6 months.
