Francis, the answer is in YOU. Not anyone else, including the wife.
No relationship is going to make you happy unless you are happy with yourself....
My ex's grandmother used to quote a nursery rhyme all of the time:
"If wishes were horses, beggars would ride."
You aren't a beggar and you aren't gonna ride. You're gonna have to walk through life on your own two.
So, what do you want in your life? How can you get that? What did you learn the first time you were posting here? Is there a history someone can look up and help you with perhaps?
