Most Helpful Guy
If he seriously wants you as much as you want him then he'll come back, and if not then its a good thing that it did end, because imagine the troubles it would cause if you're in a relationship and he's not commited1
I don't think it was a mistake at all. You say he was flirting and you weren't going anywhere. The way it was, it was just causing pain and frustration for you. There is a chance that if you allow him to miss you (i. e. cut all contact) he will realise that he wants to be with you. That won't necessarily be the case though, so don't hope or wait. If it happens, it happens – if not, then you're better off without him since the situation obviously caused you pain.
