boy advice needed

There's this guy and we dated Briefly during the summer then he met someone else , we didn't get to see each other much and I was moving to a different city etc we stayed really good friends and talk most days the other day he mentioned something about us hooking up again but I'm not sure it was a joke or not and then went on to tell me that he's not seeing anyone, then it went back to normal talking about when I was down for half term an all that ... I really don't know what to do I just can't seem to get over him at all. I've tried getting with anyone else feels wrong like the thought of it makes me feel sick, I can't throw anything to do with him away, he always makes me laugh and I'm happiest with him because I'm completely myself around him and I just don't know what to do. He's always there for me regardless and is the most supportive person. We always had inside jokes and sang in the car and stuff like that he was just everything I wanted and needed in someone, he was my goofy other half. I just don't know what to do I can't see myself being happy with anyone else and I honestly think he could be the one but I'm really unsure and scared. I think I need to hang out with him again to work out what we both want ? What do you guys think?
