Oh Bummer about your BM - that is too bad! Wow - about your sister. . . I'd be upset if she made a decision like that knowing you already paid and she didn't bother to tell you!??!! I dont really know what to say that might be helpful - sometimes you just have to be upset for a minute to really get over something! Take a deep breath and a BIG gulp! In the end you will have a AWESOME wedding and it will be exactly the way it was meant to be
