Good lord. Don't play anymore of his manipulative games. Ask him outright if he'd like to try again and become exclusive bf/gf if he says yes, then try again but make sure that the same issues that made you break up before have been resolved because if they haven't been, then you'll just break up again and be hurt all over.
If he doesn't answer your question with either a yes or a no, tell him to to stop contacting you then and get on with his life without you. Then don't contact him again. Let him contact you when/if he wants a relationship as you're no longer interested in his indicision and mind games.
If you actually stop and think about this if he wanted to be with you, you've given him every chance to do that yet instead of being with you, he plays mind games and confusies the crap out of you. pfffft. to him.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
