You should think that the girl he dumped you for rejected him,and he is trying to save what he had,before he has nothing.<br />
You should hold your head high, and tell him,,,,Damn ! Sorry about your luck. See ya!
Honestly, he probably lucked out with another girl and thinks you're desperate enough to go back with him. Say HELL NO ! :)
Maybe he has seen the error of his ways, but more likely he kept you as a back-up plan.
He could just truly like you for many reasons, but felt the relationship wasn't going to work in the long run.
Whoever he dumped you for has dumped him?
