My wife has OCD

My wife has OCD and constantly criticizes how I eat, walk, and dress, trying to "fix" me without showing affection. We've never had s*x and had 7-8 hugs, 3-4 kisses from past 3.5 yrs.

I never had any relationship before, still virgin and these conflicts making me frustrated. Living like roommates but most of the financial things,

I am taking care. She is still in touch with her ex and speaking to him for every 3-4 days and msgs in whastapp and clears the chat. She never told that her ex(so called well wisher) called

and talk to her. I stopped focusing on anything, gained weight, lost intrest in life, living like a robe without emotions. Don't know what to do.
Looking for suggestions pls.
