My wife wont let me touch her , is it because of menopause?

That would be a better thought than 1)- she can't stand you any more, 2)- she has a boyfriend or girlfriend (or both) and is saving herself for him, her, or them. It also maybe because; 3)- you are distant from her and you guys are now so far off you can't communicate. I vote for #3 considering this would be a question my husband would want answered before he decided to leave or get a girlfriend.
