The road map to get through this, stop trying control her, stop smothering her. Let her live her life and make hr decisions even if you don't agree with those decisions. Difficult but doable.
She left the man you are right now. She's given you information on what was wrong. Use that as the roadmap to becoming the new and improved you.
When you take the pressure off her, and begin to change she may look at you differently and she may decide you are too good to let go.
No guarantees but you will come out a changed man.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
