How do you know if your ex friend has moved on and doesn't want to get back together?

Why bother waiting around to find out! Get out there with friends and get noted socially and eventually you will meet some nice guy. In the meantime it's possible your ex could come back if he sees you aren't losing any sleep over him.

AnswerWho cares? The minute he gets into a relationship, you have assume it's not a rebound and move on. Go out, meet some guys. If it is a rebound, he'll come running. But instead of lingering, enjoy yourself. Answer

If it is a rebound and he does come running to you afterward then you would be in a double rebound. He would have been using that other person to get past you. He might just be coming back to you because he knows he can, its easy and comfortable.
