I'm really upset that one of my bridesmaid and groomsmen not coming to my wedding anymore because they are upset that I am getting married one day before their 1 year wedding anniversary. The only reason we picked this date was because it was the only time in the summer that worked for our families. She told us that she is planning to have a party with her bridal party on our wedding day to celebrate their one year anniversary and my fiancé was one of their groomsman!!! This really suck because her bridal party are our friend too and we are worried that our friend won't come to our wedding because the already RSVP to her party

I don't understand why she is being so mean, and I think this will be the end of our friendship because I cant look at her in the face without feeling really hurt and pissed. What should I do?
