BG, my gut tells me that you do not need to be involved with this woman. What does she want from you? to be your friend? to have you as a babysitter? to play nice so that B can go from you to her and you won't mind?
I think it's good that she's trying to apologize for the hurt she's caused; but if she ain't trying to stop it,what good is the apology? It's like the bank robber apologizing for robbing the bank and telling them I'll be back next week to rob you again.
If she needs to make amends to you for what she's done, great; let her do it in an e-mail or phone call or in person, whatever you guys choose. But when that's done, I don't think that YOU should have any more contact.
I'll go back to our common theme here, Worry about BG and let H decide what he's going to do.
