Choc, Ya know, I bet it is the other way around to her . You being moody and grumpy makes her desire you less, which in turn makes you moodier and grumpier, so she desires even less and so the viscious cycle goes. The moodiness and grumpiness is fused behavior, you are depending on other-validation to pull you out of it. If you can pull yourself out of that mind set and find a way to self-soothe, maybe you can break the cycle, KWIM?
Not easy, I know. I've also become a grumpy old man before my time, and that I am trying very hard to work my way out of regardless of what MrsGGB does or doesn't do. So yeah, I understand what you are saying, but I've also learned through this board that it is MY problem.
