How do I find out if this guy is actually interested in me?

Matched with this guy on tinder at the beginning of April. We live about 30 minutes from each other at home and go to college an hour away from eachother. We Snapchat pretty often every day but we don't text or call. We've had crazy schedules since we started talking back in April so we actually just finally got around to meeting in person a few days ago. I was the one who offered a hang out. I had a really great time, he was even cuter in person and we definitely had some great convos/found out we're pretty similar. Neither of us will be home until July (we're both working summer jobs at our colleges) so there's a little bit of distance between us again until we're home. I told him I had a great time and he said he did as well, but we didn't even kiss or hug and I'm starting to get scared that maybe this is just a totally casual friendly thing vs him being interested in legitimately dating me. When we first started talking he flirted pretty heavily but I. D.o.n.t know if I was directly flirty enough back and he hasn't really been like that since. I've tried to turn it up a little but I'm scared to be too forward because I. D.o.n.t want to seem to aggressive and scare him off. But I'm very interested in pursuing something with him. I just don't want to waste too much more of my time if he's not interested in me that way, so any tips on how to find that out without scaring him off or being too direct??
