Know someone who keeps going back to their ex?

They break-up, they're back together...they break-up again, and get back together! Sound like your friend? Or maybe it's YOU! Are you tired of your friend constantly breaking-up and making-up with his or her ex? Think he or she should either stay together or end this relationship for good? If you or your friend is guilty of the "boomerang break-up," we want to know!
