Yesterday, one of my bridesmaids facebook messaged me that she feels like it would be inappropriate for her to be in my party any longer citing that I had "kept her out of the loop" and that I was being irresponsible because I was depending on others to pass along information, such as a bridal get-together to try on dresses and go out to lunch. She also mentioned that the wedding was starting to sound too expensive for her current lifestyle because I had planned a bachelorette party in Chicago and talked about the potential idea of the guys renting or buying suits instead of tuxes (her husband is standing up for my fiance).
This came as a complete shock and surprise to me, because I never asked anyone to relay information to her. I was hand-making cards for the get-together and was passing them out to my five bridesmaids individually, and hadn't gotten to her yet. My bachelorette party is not in Chicago, we are bar-hopping in a close-by city with a designated driver. The idea of buying/renting suits was just that: an IDEA.
I'm hurt and angry about her decision especially considering it means my fiance will be responsible for asking one of his groomsmen to step down to keep the parties even. This situation also brought to my attention that my bridesmaids are gossiping about me behind my back, and I have a fair idea of who is. I don't know how to address the people involved and am unsure how to cope and let the bridal party know we are one less. My fiance is supportive and is convinced I did nothing to deserve this reaction. What should I do?
