It sounds she's over the "angry stage." She could be acting nice just to make the D easier, but use this to your advantage and try to work on being friends. It's unlikely she's going to change her mind on the D soon so don't expect that. DBing can take a looooong time. Do not pursue.
Definitely don't share anything negative that anyone says about her. You only want her leaving you with positive thoughts.
There is no arriving, ever. It is all a continual becoming.
