Advice | Ask Amy: Should I be the best man if I think the bride is abusive?

Dear Amy: My very best and oldest friend, “Curt” is getting married to his longtime girlfriend. I have spent a lot of time with them, and I can say definitively that Curt’s life is much worse since they have been together. His fiancé is extremely controlling and has him on a very short tether. Recently he told me that she threw a shoe at him in a fit of anger.
