Did he just want sex or is this how casual things happen? Feels like he's happy with it being a one time thing?

Okay so i have this new guy friend who I always thought had a crush on me in the way that he interacted with me... Very flirty and very over touchy feely. For AGES though, near enough a year of flirting. He arranged this hang out, bought all my favorite food, booked an activity for us to do that I love...

We ended up in bed together... Completely sober after hanging out together. We had sex like 5 times that day/night. During the last time, he didn't finish. He actually stopped having sex because he felt like he had to throw up (which he did during the night I stayed there). I don't know if this actually happened but I also felt like he was less hard than the other times.. so iM thinking he might of stopped also cuz he couldn't keep it up...

Anyway after we had sex the first few times he was like holding me and kissing my head, saying how much he liked me. During the actual sex he was very slow and romantic and said my name making loads of eye contact.

Cut to the morning after. He's not slept cus he said he was up being sick (did hear him do this tbh). He was moody... No affection really. Didn't offer me anything to eat/drink. But did drive me home which was quite a while away.

Since then... Zero contact. I did text him asking if he is okay with his sickness and he said he was getting better. That's it. No more conversation whatsoever. So I didn't reply.

... Basically he just wanted sex didn't he?
