This will come off harsh but you are asking for honest input from the "other side".

We probably understood if far better than you did at the time and we probably still understand it just as well now.

With that said, congratulations on your sobriety. It sounds like you're...sorry.
I know it's good to end letters with some sort of an action plan. Many of us found leaving our A's to be the single hardest thing imaginable. Once we've made that decision to detach, break up, divorce, etc., hearing the request to speak again would be at the top of my no, no list.

I don't know how to get around that but I noticed I was triggering on that wish of yours and I wouldn't have wanted to see that coming from my A. If you're really sorry about your actions, leave it at that and try not to invite further interactions by speaking to one another. If she finds your letter sincere, she will do what she wants but just proceed with caution. Our wounds are huge and take a very long time to heal.
