Everyone has a sappy break-up song

Whenever you go though a break-up, there is the ceremonial break-up song that you listen to over and over again like the number of times Marcia Brady got hit on the nose by the football right before her big date with Davey Jones. You listen to your  break-up song in the car, on your iPod at the gym, at work, at home in the place you two shared. We all have a break-up song. This is mine with Matt, "Bubbly" by Colbie Caillat. It's a happy song I know, but for some reason it's the one I can't stop listening to.
