I think you're amazing. And call me a big softie but I have a tear in my eye reading that. You said you needed to say those things and you did. I sorta did the same thing once I apologised for things I realised I had done wrong (we NEVER talked about our problems or issues) and he said why are you doing this? I said look even if we never ever get back together I need you to know that I'm sorry I treated you that way and made you feel that way. I think it's important for both of us to heal to know that.
I thought your letter was beautiful. I don't know if it's DB'ing or not. But it sounds like you offered her selfless love and support.
In my sitch he said all types of things and it made me sad. I worried that he would GAL and when he started seeing someone it hit me like a ton of bricks because I thought I would always be the one, it would take longer, who knows. Also in the split it had always been about ME not being happy. He had been selfless etc and so when he said gosh I'm finally happy now. I'm doing things for myself this is great. It made me rethink.
I'm not saying you should date or do anything to make her think of you differently. That's manipulation and pursuit. I'm just saying that at some point I'm sure she will look back at your M, your love story, etc and you have made sure that the bridge wasn't burned.
You've given her a lot of information so if I were you I'd take a step back.
