I've never known anyone who was in a rebound relationship that lasted.
This is because when you're rebounding, you're looking for someone, pretty much anyone, to fill the hole that's left by your ex. You're willing to overlook a LOT of things that normally would set you off. Eventually, you figure this all out, and you end it.
Sometimes, however, you do find someone on a rebound who's the kind of person you would have dated anyway, and then things might work out, but that's pretty damn rare.1
