I Can't remember the name of this movie probably from the 80s or 90s about this rich women who's husband divorces her for a younger women, she becomes the leader for there teenage daughter group of some sort kind of like a girl scouts. Later her husband tries to get back together with her or she thinks because he wants to see his daughter more. One detailed scene I remember is the mother is telling either her daughter or another girl in the group about her most embarrassing moment was once at a store when her credit card was denied and the sales girl cut it in half right in front of her. Does anyone know what this is called?

Sounds like "Troop Beverly Hills".
