Your statement of "that her body is NOT doing the things she wants it too." is pretty presumptuous. Saying something like "she's unhappy with herself" or "unhappy with the relationship" that would be pretty accurate in my estimation....but you don't have any way of knowing if your W or any other woman is unhappy "that her body is NOT doing the things she wants it too."
That sound like you projecting again. Just speaking frankly...it sounds like that's what you think she should think.
