Dear Abby: I used to be close friends with "Colette." We were so close that I asked her to be a bridesmaid in my April wedding.

Over the last several years of our friendship, Colette became selfish and domineering. It didn't bother me so much before, because I felt her positive qualities outweighed the negative. However, after several recent incidents, I finally told her I was upset. She offered a cop-out response, and we have not communicated since then. That was a month ago.

How do I let her know that I want to withdraw my request for her to be a bridesmaid? I don't want to hurt her feelings, but my wedding will be a small, private affair, and her presence would be painful and disruptive to me and another bridesmaid who recently had a similar experience with her.
