One of my b.m.'s was inadvertently elected to be in the party by one of our big-mouthed friends. I have only known her for about 1.5 years and every other girl is either family or childhood friends. At first she was so enthusiastic about it that I settled. Well, lately, she has been distant and busy. We hardly ever hang out and only talk online. Those conversations are limited to her frustrations regarding dresses or how I'm handling things wrong. I just don't feel connected to her as much as I'd like to. Personally, I think that 7 bm's is too many. My fiance can only gather up 6 tops so that's another issue. Now, this girl is very sensitive and can be very defensive. What do I say? How do I even preface the conversation? And is it completely wrong of me to demote her to another role in the wedding? I'm afraid to lose a friend but at the same time, I don't know we'll be friends for life at this point. At lease not enough to have in my wedding pictures 20 years from now. please help!
