But this is why the whole narrative of YOUR WEDDING IS THE MOST IMPORTANT DAY OF YOUR LIFE AND YOU MUST MAKE IT PERFECT AND MAGICAL AND SPECIAL!!!!!! is poison.
Of course, selfish assholes are selfish assholes; sometimes selfish assholes also get to be brides. Somehow, despite our cultural wedding obsession, every wedding I have ever attended — including where I was a bridesmaid! — were not actually put together by proto-Stalins in white dresses. I maintain that while putting weddings together is basically designed to be super stressful and probably causes almost any bride at least one emotional meltdown, the vast majority of brides who were thoughtful and normal human beings before their engagements continue to be thoughtful and normal human beings during the wedding planning phase. Heck, I went to one wedding where the chosen venue — which was in a small town and booked a year in advance — was shut down for tax issues the day before the scheduled ceremony. The bride was of course not happy, but she didn’t flip out; she just focused on finding a new venue, and on we went.
In other words: Bridezillas are actually few and far between, and any normal reaction to the stress of planning a big event is typically cast as “bridezilla” behavior. Really, the women (and men) who are terrible jerks about their wedding are terrible jerks generally. The wedding industry, though, does not help. And it’s totally unclear to me how this particular woman even had 10 friends to ask to be her bridesmaids to begin with.
