Do you mind if I pop in, settle into this cozy easy chair with a nice steaming mug of hot cocoa and make a suggestion? Make a list of good things about your w to help you try to focus on the positives about her. Even things that appear to be non-r related, like being a hard worker, dedicated to her job, etc.
I think the WAS (and those that are considering being a WAS) dwell so much on the bad things that all of those good qualities that we all have fly way off of the radar screen. In my sitch, I've forced myself to try to focus on the positives and not let the negatives cloud my experience and my perception of my h. Believe me, if I wanted to dwell on the bad, I probably would be divorced by now.
