Cuddling and making out at prom after party.

I didn’t go to prom this year, but I went to an after party at a friends house. There was a guy there and we’ve kind of talked to before but it never went anywhere. His prom date was there, but he seemed to pay more attention to me. Everyone was drinking, but this guy stayed sober. I normally don’t drink, so after a couple drinks I was very drunk. Throughout the night, he would ask me if I was doing okay and would put his arm around me and hold me. He didn’t do this to any other girl at the party, even his prom date. At the end of the night, we ended up making out before falling asleep cuddled up together. What does it mean? Was he just trying to hook up or does he have feelings?
