You are the only one who knows you, what you need, and what it takes to get you through as well as you do.
I understand your sense of reasoning for sending a letter to your xh, and on many levels it makes sense.... However, I do believe it may cause more discontent than tie up the loose ends that maybe sitting in your way.
I think it will slam the door on any communication, which on one level is what you are looking for, it I'm afraid it will dredge up old guilt where the xh is concerned, therefore leaving him with a foul taste in his mouth, along with hard feelings.
Yet,on the other hand, you are trying to close the door to the past, and it will allow you to get those final words off your chest, I can see you being released to move forward.
As always, you come up with some hard things to think about... I myself would just quietly slip away... saying out loud to myself, good bye and good luck, it's my time now.
Most importantly, you have to do what is right for you.... no one has the right to tell you differently.
Take care of you... hugs
Jeremiah 29:11 For I know the plans I have for you.........
