Can anything good come from heartache? According to entrepreneur Joshua Opperman, the answer is yes. Opperman started an auction website called I Do…Now I Don't as a way for fiancés left at the altar to get rid of expensive engagement rings. Now, the site has developed into much more: Jilted lovers are turning to it for its social community, where they can vent about their ex or find tips on surviving the breakup. The site also features the best breakup songs (with lyrics so you can sing along) and a blog for sharing personal stories.
