I hurt my ex. I said mean things after out breakup. And she told me she wanted no contact with me anymore.  For clarification I have BPD. I had never said anything mean in the relationship,  in fact I was the sweetest man she had ever met, her words not mine. Anyway, at the time I had no idea I had BPD. I didnt know. But now that I've been to therapy, I know. I feel extremely bad about the way I treated her and I really want to explain some things to her about it and apologize. Has any one had success as someone with BPD sending the letter? And if you are a partner or ex or someone with BPD my question is, if  I or your person wrote a letter explaining everything that i/they know now after being in therapy and how they felt after being apart for 3 or 4 months, would you have preferred a letter that explained everything and why I said the things I said and why I was the way I was, for you to read when you were ready to this being a long letter, or would you have preferred a shorter, more condensed, "I'm sorry, you were right about a lot of things, I'd like to talk and explain things when you're ready" letter, if that makes sense? Is it even possible she could ever want to talk again?
