I haven't welcomed you yet Galileo. So, Welcome.
Your story really made me stop and think about my own situation in life. My wife hasn't moved on emotionally, yet, but I know the chance exists. You've been through a lot and I give you credit for keeping your sanity and I really appreciate your posts.
Hang in there. It's a lonely road you're walking. But, you will find company from some of us from time to time.
