I didn't have the courage to post my 'ah ha letter' here. I think timing has a lot to do with it. Wait to deliver until you know he is at most receptive. I waited until after daughter's big concert where I could tell he was feeling kinda guilty. But anyways, just remember that the letter is for YOU not him. And not to win him back. I was terrified but as time goes on feel really good about the raw feelings I expressed (big for me). It's very freeing and I feel like a better person for doing it because i learned and accepted so much about myself in the process.
