Telling her she is making a mistake I think might just aggravate the situation. What do I know I am here with you guys. I would say be nice and cordial. How would she expect you would react? When i told my W (after a blew up about the D and a few days had passed) that I respected her decisions about the D and appreciated her honesty in telling me her tune became much nicer. You want to create doubt but not by confronting.
