Jeff, Yahooo! Your letter shook up that hard shell your w has around her a little. Jeez, with the division of labor stuff. You are talking about a possible end to your marriage and she is still stuck on that stuff. She needs to move on already!
Anyway, I am so happy for you that you feel you have taken control of your life. And there are a lot of positives that came out of it.
Look into what she is complaining about with an objective eye. Validate what she is right about, agree to change what you can and go on from there.
