I have seven BMs, two of my cousins, two really close friends, two girls I dance with and a girl who really needs an older sister. I am very happy with all of them and they are all doing everything I can to help with things. I was talking to a co-worker about it and she was absolutely astounded that I didn't have my older sister as a BM, is it an unwritten rule to have sisters as BMs?
My sister and I haven't been close since I was about 6. She is currently in a relationship with a guy, who she has a 2-year-old with, who is a Satanist. He has convinced her that all churches are bad and she won't step foot in a church. Wouldn't that make the ceremony a little difficult?
