So my best friend of 7 years asked me to be her maid of honor (and I was overjoyed, of course!). She had asked her twin sister earlier, but she had said that she really didn't want to be in the wedding party, so I was asked instead.
Cut to six months later, I'm hanging out with the bride and her sister invites herself over. The bride and myself chat a little about wedding planning stuff (it was a 2+ year engagement) and move on to other topics. After I leave, her sister throws a fit about how I'm her maid of honor. Long story short, sister gets her way and the bride asks if her sister can be her maid of honor too. After seven years of being friends, I already know that she said yes to her sister and is asking my opinion after the fact so it really doesn't matter. At the time the bride said that she didn't really care about he labels of MOH/bridesmaid, and made it sound like we would both be joint MOHs.
Months later, I mention something about being her maid of honor and she says, "You're not my maid of honor, (sister's name) is." Was I right to be upset about this? Seven years of supposedly being best friends and her sister throws a fit to get her way after she already declined?
