I have a friend who I have been friends with since preschool but the past 5-7 years we have really drifted apart. We don't really ever hang out. In the past year I think she has invited me over once and she never comes to things I invite her to When I became engaged she said "i better be the maid of honor". It was kind of a joke but I could tell she was kind of serious. I already picked a different friend as my maid of honor.About a year has passed and today she asked me if a picked a mid of honor. I told her I picked another person and she was really upset. I told her it was nothing personal but she didn't care. I feel horrible and i though that may be I could split maid of honor duties between her and my other friend but I am kind of upset that she is putting me in this awkward position. I don't want to lose a friend over this but I also feel she should be more mature and understanding. I want to stand my ground but I feel like it may not be worth it to harm our friendship. Am I being selfish? I need another perspective.
