Obviously there's a whole history with your friend and his W. Maybe she realized what she was missing.
In my situation, I refuse to reconcile without my W changing as well. Even though I know another path to possible reconciliation would be to become overly apologetic, accept all blame, and buy into her narrative 100%.
I have to assume there was *some* change, although I don't know what. And I agree - while there are many things I'd have done differently, the issues that caused our S were not 100% on me, and therefore any sustainable reconciliation would have to be the fruit of both of us accepting fault and making changes.
This shouldn't be a surprise, but in MC, we've definitely both articulated areas in which we contributed to the S, so it's not as if WAW is putting all of the blame on me or anything like that.
