I need some advice on the right thing

So there’s this guy I’ve been hanging out with, we like obviously like each other and we’ve made out and spooned while just laying on the couch and talking. From what I can tell we have chemistry and it’s great. Here’s my dilemma. I am leaving in a month to like in a different state (5 hours away) and staying there for 3 months before returning. Literally all I want to do is be with him and it’s so hard not to. Idk if it’s just lust but it feels like more because when I think about him with other girls I get a little hurt. should I pursue it and see what happens even if it’s just a pent up sexual tension hookup or leave it alone and fight every urge in my body that’s telling me to jump.

Update: I’ve decided it’s too hard on both of us to start anything now and I’m going to wait till after summer to see where we stand
