Hi Luther, it's good to see you post again. I encourage you to post more often. When you go several weeks with no word, we think you've left.
The more you can tell us about the history of your M, the better picture we will have. Can you tell us more about the breakup years ago? When she says you didn't change, what changes did she want to see in you?
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!
