DEAR MISS MANNERS: It used to be the bride who proclaimed that the wedding was Her Day. As soon as that attitude resulted in many of them being called “Bridezilla,” everyone else started popping up to proclaim it Her Day (or The Couple’s Day). Does the mother of the bride want to exclude her ex — who treated her abominably in the divorce, and who isn’t related to nor close with the bride — from the wedding?
