I chose my close friend from college to be my MOH. She has always been there for me. I have a friend who recently asked if she was going to be my MOH. She and I go way back but sadly our friendship has been a one way street. When she asked me, I was at a loss for words and just said I hadn't really thought about it much (at that point I had already made a choice). I wasn't prepared to respond to her comment and didn't want to hurt her feelings. I was also surprised that she even wanted to be in my wedding because a while back she was in a friends wedding and complained to me about planning the shower and buying a nice gift.
How can I tell her in a kind way that I have chosen another friend to be my maid of honor?
