I always presumed DOM was a sub/DOM reference too! That makes more sense now 
Been reading and trying to keep up with you all but not getting any comments in before it all moves on!
Haven't been counting my NC days but it must be about a month now. Still having some very dark days and last night I wrote an email in a 'write it but don't send it' way apologising to my XDP for my part in our crappy relationship, taking ownership of my own problems and telling him that I know I made the right decision to end it, but that I still miss him.
This morning I reread it and then hit send. 
Not sure if I want him to reply TBH. It was more to get it off my mind and I know that however he replies it won't be satisfying so it might be best if he doesn't. He's not going to say "it wasn't your fault, I was a verbally abusive shit to you and you deserved to be treated better" so maybe its best if that is it. Either way, I'm trying not to give a shit when I get an email notification, but as you all know that's easier said than done.
I do feel better for having sent it though. My counsellor said it doesn't matter if he thinks badly of me, because its not true, but I don't want him thinking I'm a selfish arsehole and he's happy to be without me. I want him to remember me as someone flawed and real, but with the humility to accept that I wasn't perfect either, even in the face of the horrid things
he said to me. I still didn't deserve to be called a cunt or goaded and mocked, but he will never change in that regard as he's a narc and that's what they do. At least I can feel lighter having got it off my chest.
