I met a really awesome guy but I don't know if it's realistic to pursue anything with him, help?

I'm 19F, college soph, he's 19M, college soph. we matched on tinder and I could tell we were pretty similar, and after some convincing he ended up getting me to come hang out with him (ive never met up w someone from tinder). we hung out for almost 4 hours, went to the beach and kinda just drove around. he's sooooo cute, and he's super smart, funny and charming. we share a lot of the same beliefs and have similar political views which is awesome. he was super respectful and we kissed but that was it.

here's the issue, he was only visiting the town where I go to school for the weekend and left this morning. he goes to a military academy about an hour away from where I go to college. and, his home state is about 3 hours or so from mine. so, obviously, there's kinda a lot in the way. I've done long distance before (almost 3 years to be exact) so I know it's def doable but I know it's not everyone's cup of tea and don't even know if he'd be interested in something serious because of this. his school is obviously super strict and the times we'd be able to see eachother would prob be limited.

so, what should I do? it kinda sucks :(
