Hairy, I'm so glad she's going. This might be the first tiny step of millions that will restore your M.
As I was reading your first post, I thought, This woman is scared to death to be told she's wrong.
If you know that, and know how vulnerable it makes her feel, you can go into the meeting with compassion in your heart for the difficulty she will be going through.
All the while maintaining your new steely persona and not letting her off the hook. She won't like hearing that she's not perfect but she will be a better person in the end. Hang on tight to her so that she realizes that your love is still there, even though she has big time warts.
