He says he doesn't know what he wants. What does that mean and what do I do?

my ex boyfriend and I are thinking about getting back together. we dated for a year and then we broke up and its been about three months or so since then. since we broke up we have talked pretty much everyday and stayed really close friends. we have even kissed and made out since. but recently I told him it felt like he was leading me on and stuff and I needed to know if he really wants to be in a relationship. he said that he really wants to date again because whenever we hang out its special and stuff but he doesn't know if we should. he says he doesn't know what he wants. what does that mean? and where does that leave me?
