You absolutely deserve some happiness with someone loving, caring and devoted. NoCode attends a divorce support group (maybe he can comment on that). Have you looked into that in your area? I would find it helpful (just like this site) to get together with folks in similar sitchs if I was separated.
How is your D doing? Does she still spend time with your W?
