Why did he ask for a 2nd date in person and then change his mind?

Went out with a guy on Friday and had a really great time. Convo was good and then went dancing and stayed until the bar closed. He ended up staying the night. He kept saying how he hasn’t had this much fun in a while and talking about a 2nd date. He kept saying “next time when we hang…” and then also as we were leaving asked to hang again.

He texted me the next day and asked how I was feeling and thanked me for showing him around. He then said he will let me know if he’s ever back in the area. Now that threw me for a loop. I thought there would be a definite 2nd date. He sent me a few more message and haven’t heard from him today at all. What happened?
