I don't think it serves any of you to try to correct her or be in any kind of way anything more than what they ask for and it's okay to say, "No," too.
You've decided she's not your sponsor in actions, but you don't have to verbalize that. You also don't have to do anything you don't feel is good for you.
I'd say, keep it short, do a nice thing if you feel you can, otherwise just listen. Ranting, bargaining, denial, and being angry is where they are right now...but you don't have to be angry with them.
God meets us where we are.
This is a good thing to discuss with other Al Anon friends, too.
