I like
"She's a million miles away across the bed"
because it can apply to the woman in the affair now being so far, but also his wife/partner being right next to him yet so distant in their relationship
I also like
"It's the way she doesn't try"
because, again, I see how it can apply to how the woman in the affair was so effortlessly attractive, but also how his wife/partner doesn't seem to try to work things out anymore in the relationship
