Undefeated,

First of all, the letter is way too long. I read about half and got tired. I'll read more of it later. From what I've read so far the letter is good FOR YOU. It gives you direction. So keep the parts that show what your goals are for you, and put it somewhere you will look at it to remind you of your goals. But that's not of great interest to him. Secondly, stop saying he is not your husband. Emotions come and go, legal status is a lot harder to change. He is your husband whether he wants to admit it or not. He is your husband, you are his wife, those are your kids, and the two of you have to deal with it.

I will take a break and read the rest later.
