I need some help with a tinder guy

Ladies I need your help. To make a long story short I hooked up with this guys from tinder we had a great time, or atleast I think we did. We had been talking for the past 2 weeks when I decided it was time to meet him we ended up back at his place and we did not sleep together but we did do other things. We put on a movie afterwards ate some dinner and he invited me to stay the night. Next morning was a little bit awkward (he lives in a fraternity house ) and I felt he was a little less welcoming I guess? Anyways I left and we haven't talked since it was only 2 days ago but I genuinely want to see him again yes to keep hooking up but also see if it goes anywhere else. How do I approach the situation should I keep waiting for him to reach out or should I say something first. He's 2 years older then me we are both students at the same university but otherwise have no connections. It is exam season so we are both very busy. What would you girls do? Call it a great one night or make an effort to try and see him again.
