We just had sex and I think I like him. What do I do now?

I just had sex a few days ago with a guy from the first college I went to years ago. I had the biggest crush on him at the time. About 6 years ago we ran into each other in the city I moved to about 8 hours from where we went to college together (to attend another college) and as we were hooking up in the living room, we got caught by my roommate which basically ruined it and he left completely embarrassed. Needless to say I didn't hear from him after that. Fast forward to January 2017; we reconnected through a dating app that we are both on. He saw my profile and sent me a message on it, nothing flirtatious, just a simple hello and how are you. We ended up exchanging numbers and have been texting ever since. There was not even a hint of flirtation in the texts from him. However the texts we were exchanging soon reminded me of why I liked him; he could still make me laugh. I ended up inviting him to a dinner party at my place with a small group of friends. He accepted the invitation and came to the party. Before I knew it, he was the last guest left and we were listening to music and talking. The next thing I knew we were standing in my living room and he locked eyes with me and kissed me! It was the sweetest, most tender, yet passionate kiss I've received in a long time. Naturally, things progressed to the bedroom and lets just say, neither one of us got much sleep and the full box of condoms I had in my night stand was almost completely gone by the time he left the next day at 4pm. I can't remember the last time I felt so taken care of during and after sex. We took a shower together and I made him lunch. While I was washing the dishes from lunch, he learned that he got a karaoke hosting job that he had interviewed for several days ago and was so happy about it that he picked me up and spun me around. He would have stayed longer but he ended up having to go start training for the new job. I could tell he didn't want to leave.Our last interactions before he left we're so lovely and affectionate, including him giving me a back massage. As he went out the door he turned around and locked eyes with me and smiled and said bye.
