Advice. Well, how are you feeling? I hear pain in your post. Worry? Sadness? All over something over which you have no control.
Take a look at some of the posts the last few days on my thread, especially those from Coach. They really make sense. And, the best part is, they have gotten me to a very peaceful place. Not unemotional, but a place of strength and calm.
Take a look at the concept of cognitive dissonance (wikipedia's got a great summation). Really think about it. It will help you understand what your W is thinking and, more importantly, what and why you are thinking and feeling the way you are. BIG concept for me. And a turning point, I think. I learned how to stop my negative emotions by simply changing what I was thinking.
Really examine where your focus is right now. It sounds like it is squarely on your W's actions. Dangerous. Setting you up for a fall.
Letting go may not be easy, but it is liberating. And it allows you to act the way you should (you know, the I'm already dead approach).
Trite as it is around here, focus your effort and energy on you and your kids.
