I'm thinking of this more in terms of helping her to heal... I did ALOT of crap to her over the years... regardless of outcome now... and the fact that what she's doing is all on her... I still want to help her heal if I can for the past.
Quit thinking in those terms. She doesn't want anything from you right now, ESPECIALLY help with anything. Your job is to remove yourself from her life as much as possible. Give her time and space. Do not help her with anything unless she specifically asks, and there are some here that feel you shouldn't help even if she does ask (the thinking being that if an OM is involved then you're just being used, which I don't disagree with).
