I've been friends with one of my bridesmaids since the 2nd grade, and I know she has always been odd and arrogant, but I never let it get to me. So, this past weekend we went wine tasting for my bachlorette party and while we were having a drink at a bar after dinner she lost it. The entire weekend she looked miserable and showed up super late and was rolling her eyes at the other girls and myself but we just ignored her and were still nice. But once we were at that bar and we were only on our first real drink of the night and some guys started talking to us and wanted to get us all a round of drinks, so we were all being friendly and having fun, expect the one and she had her arms crossed with a sour expression on her face, well one of the guys said something to the girl and she started swearing and called the security guard over and then she ran out of the bar. She took a cab back to the house we were staying at where my mom and aunt were and was then swearing at my mom and saying that the other girls and I were whores and being inappropriate and stormed out of the house, throwing and pounding on doors, now she wont respond to calls or texts and I don't really know what to do. But I am really shocked and mad since, no one was even drunk and we were standing around talking, it was all pretty tame for a bachlorette party....any advice? And my wedding is in two weeks.
