Is this hooking up or more?

Been spending time with this guy and he calls it just hooking up but he asks me to spend the night and next day with him, takes me to dinner, we hang out and watch movies, text all the time. Forgive me if I'm wrong but isn't hooking up just sex and ya leave? Dude is sending some mixed messages.

I've never had a "hook up" like this. It's confusing lol
