My sister, who is also my MOH, has been a complete nightmare when it came to planning my wedding. I will spare some details, but to keep you up to speed: 1) she did not want to look for bridesmaids dresses, when she did she refused to try the majority of the dresses that I liked on. 2) EVERY detail she has told me she didn't like from the cake flavors, to centerpieces, to bridesmaids shoes, flowers, location, etc. 3) she has screamed at me that she doesn't like my fiance. I am at wit's end with her and I don't know what to do. Do I ask her if she wants to be a part of this? Do I ask her to step down? What is she going to say at the reception? Can I ask her to not be my MOH anymore?
