My bridesmaids are 3 of my good friends and my finances sister.
Yesterday my fianc and his sister got in a huge fight, and she said some very offensive things about my maid of honor/best friend apparently she's been talking bad about her for a year now, calling her ugly, making rude noises and comments in general. My MOH is the nicest girl and would never purposely upset anyone, but she's currently dating the troublesome bridesmaid's ex my MOH didn't know this when they got together. So she automatically hates her.
My fiance doesn't want to talk to her anymore, and the fact that she spoke badly about my best friend infuriates me. I can't think of having a good time at my bridal shower or anything when I know she's going to be sitting next to my MOH thinking bad things about her.
However, she hasn't been rude to me or my MOH to our faces, and if she's going to be my sisterinlaw I'm going to have to see her a lot. I'm not sure whether to kick her out, or to bring it up to her somehow.
The wedding planning is still in the early stages, they haven't bought their dresses yet.
