"It's not you, it's me" is a breakup strategy that might work for George Costanza (who also claims to have invented it), but it doesn't tell you what "It" is. Enter WotWentWrong.com, a new site that allows recent dumpees to send a short message to their exes to ask that very question: What happened?

Users fill out prewritten templates that range in tone from "confused" to "flippant" and are given the opportunity to customize the messages before they're sent to their now exes. "We're providing a socially acceptable way to tie up the loose ends, learn from what happened and improve your dating Zen for the next relationship," founder Audrey Melnik says. "No stalking required."

Would you use the site to contact an ex?
