I agree, do not use examples . Doing that is like teraing open old wounds. You said he has PTSD right. That might not be the best approach in this situation. It might just fuel his hurt,anger etc .

Maybe you can wait to send this letter or write this letter when things are not so fresh right now, and you are not so numb?

Hamster if you really do want to write and send a letter, just go from the heart. He knows whats been done, so no need to use examples.

I would write about how I feel now, about being remourceful, sorrow, and acceptance. I would write about your intentions and make it clear, your intentions about what you want. And how you are working on self love and forgiveness of ones self.

Scince he told you that he wants you to detach from him. Maybe writing a letter at this moment isnt the best way to show him you understand and respect what he has asked for. Maybe it would be better to show him with actions instead of words .

And if you are feeling nothing right now, then maybe it would be better to wait on this untill you are feeling something . I have a feeling he will see this letter as a way to manouvre around what he asked you for.

What is your gut telling you about this letter Hamster?
