Let him go, or not?

Hi guys. I recently got in touch with a guy I liked in High School, or he got in touch with me.. I can't remember, anyway.. I found out the feeling was mutual, but we didn't do anything about it, as I was very shy. 5 years went by, we moved on, he moved away, now he is back. We met up, and 3 months have now passed (he's here for the summer, back at Uni soon) and it has been wonderful. We have spent every moment together, many dates, i've met his parents, he's asked to see baby photos, we talk all night, have so much in common, I just adore him, and we have been intimate, but he never pressured me for sex, and we haven't had sex. I see him a few times a week, for days on end. He tells me he likes me a lot all the time, and is very caring and kind to me. We really click. He wants to know everything about me, and remembers everything I say. Anyway, he is going back to Uni soon, and I asked him after 3 months, what we are, cos' we haven't labelled each other. I have come to a point, where I am falling for him hard, and want to know what the deal is. We are certainly more than friends, and this feels more than casual. He was in a 5 year relationship, which was very hard for him, and ended badly. He told me he likes me a lot, and likes things the way they are, wants to continue things, for now I guess, and said he just got out of that long relationship and doesn't want a relationship clearly. I don't know if ever with me, or if he isn't ready. He told me he has no intention of seeing his ex ever previously, and she asked to, but he refused, so I know he is over her. I can feel he likes me. He also said he's just moving, he isn't dying, and he isn't that far away, and really wants to to keep in touch. He even wants to go away with me this weekend. I don't know if I should just continue enjoying his company until he goes, and just play it by ear then, or cut it off now, as I am scared of getting hurt, and sometimes think perhaps I should get out, if he doesn't even want a relationship, as I am not into casual things, and am really falling in love. I am already feeling uneasy, and don't know what to do. He is moving about 140 miles away, and for a year. Help please guys! Advice and such.. Thank you.
