I recently went to lunch with my fiance's sister-in-law. We get along really well but are not very close. Right at the end of our meal she asked me if she was going to be one of my BMs. I was completely thrown off and told her I hadn't decided what I was going to do yet.
I originally had planned to have my best friend and my fiances sister (who I am VERY close to) as BMs, and that was it. I don't know how to tell her my plans without hurting her feelings. Or maybe I should just let her be apart of the wedding? Please help!
