Dear Annie: We belong to a dinner group with six married couples. One of the couples divorced after the husband caught his wife having an affair. He no longer comes to the dinner parties, but the ex-wife still shows up and brings her new (married) boyfriend. They have been together for three years.
Here’s the bigger problem: She flirts with my husband at every social activity. She always gives him a hug when we run into her. He is always pleasant and chats, when I’d rather he was less chummy. One time, on New Year’s Eve, I saw my husband put his arm around her waist as she moved to the music with another man. I watched (humiliated) as the three of them swayed back and forth.
