I think when he feels attracted to you he mentions divorce, b/c he's scared that you're drawing him back in. He's scared to be drawn back in b/c he doesn't want to go back to the mean old you, he likes the new nice you, and that's who he's attracted to. So when he get's a glimpse of the old you, like when you don't "shut up" then he throws that in your face, to hurt you as he feels hurt by you leading him on that you could be anything but the nice new version of your self. Stick to the DB rules. It's working.
PS....I'm sure your friend loves you too, that's why she spoke to you half the night. That's what friends are for!
