Hey, I'm sure what you wrote feels good but don't send it! What do you think will be the response? He's not gonna fall on his knees and beg forgiveness or even change his ways. I say if you have issues with his performance re child care arrangements etc. then deal with that in a polite, businesslike manner. The other stuff is just saying "you've still got the power, baby" If you say what you would like to see in regards to the above mentioned issue then that is boundary setting. Don't send a "poor me, how you've treated me so badly" letter, text, whatever...I do love every word you wrote though and do understand the feeling behind it! Btw, what happened to the Cardinals yesterday, bad bird seed?
