Do NOT assume that your wife is not having an affair. I made that mistake too; "after all, this is an asexual woman, right?"
Wrong. She had an affair with her 29 year old personal trainer.
It is a paradox of life that a woman can be at the same time cold and distant, and yet starving for attention and even affection. She may be finding it elsewhere. You at LEAST need to look her in the eye and ask her if there's someone else.
