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!
It's certainly possible to like someone without wanting to continue an ongoing intimate relationship with him or her. The question is how you feel about it. Do you want to be friendly with him?
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?
