We see what we want to believe; we project our emotions onto situations.
Get out of the situation asap! It will only get more and more messy as your feelings intensify. Even if you're like "no, I won't get attached" it will happen bc you're already romanticizing the situation. Find someone who is willing to give you emotional support and a loving relationship. It sounds like this guy is young and just wants one thing - learn a bit about yourself from the situation and realise that you're hooking up when you're probably subconsciously looking for a relationship.
