Boy Help

Slept with this guy while on a trip. He was my first. We met on the trip and were friends. We spent the last 2 nights together before we had to go back home. I haven’t talked to him since. The sex was great but we had such good chemistry outside of that and we could talk for hours together. I’m not sure how to get him out of my head. He obviously isn’t going to talk to me but I wonder if he still thinks of me too or if I’m just another girl he slept with. How do I stop thinking about him it’s been a month now.
