She says she just wants to be happy. In her mind, happiness means cutting me out of her life, and moving on.

I don't no how to proceed. Give her room means letting the D go through. Do I go for a legal separation instead, which would benefit her, but not help with any sort of reconciliation. Or do I just let her do what she wants to do and move on with my life?

This is very difficult, as it is happening hours after I returned from an extended trip. I should never have taken that trip. I fear the die is cast, and all is lost.
