Dear Annie: “Susie” and I are long-term friends. We’ve known each other for 40 years. My husband and I moved to another state a few years ago, and Susie subsequently followed me. I introduced Susie and her husband to another friend of mine, “Linda,” and Linda’s husband. We enjoyed many good times together, the six of us. As time went on, Susie’s husband and Linda’s husband became the best of friends, pushing my husband out and excluding him altogether.
