It's quite true that many women want to have a wedding to compete with their "girlfriends". If they are in a social clique, there is intense pressure to get married and keep up with the Joneses.
However, if they get divorced, no one says anything to them. I would demand all of my money back (plane ticket, gift, etc) because the marriage was obviously a sham and they just wanted attention. Let's face it, women dream about being the center of attention at their wedding. After they actually get married, there's tons of disappointment when they realize they have to be married now.
With Facebook attention wh0ring, you'll now see a bunch more short lived marriages. The high that people get from posting their wedding pictures online and getting likes is as addictive as crack.
