It makes me very sad when I think about it. I feel for her. I want my happy, charming, laughing W back. Most people love her.
I hope you get what you want. It sounds as if she is searching for something that makes her feel better, even happy. It took me a long time to accept that my happiness was my responsibility, and not my H's responsibility "to make" me happy.
Can you tell us anything else about the marital history?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
