Bad move with the letter. You shouldn't have apologized for everything. Let's face it. Your W had her faults too. To dump all the blame onto yourself just made you look weak and in her head, it justifies everything she thought about you.
After reading your message, why would your W want to go back to you? You pretty much said you were a flawed person and that was that. Do you think that would actually make you seem attractive to your W? Sorry for the 2x4 but there's a reason why DB says to limit communications with the WAS. This being the main one.
"I know it will make me feel good which I think is all that really matters."
So are you saying that it doesn't matter what your W thinks? That's why you're in the predicament you're in. Would you rather do this and jeopardize getting M together? Did you actually read DR or DB? Stick to those rules.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
