So he slept over but didn't make a move, is he still interested?

So this guy I've been dying to go out with finally went out with me and a couple friends.. the night went great, we had tons of fun, and he ended up sleeping over and cuddling all night but he didn't make a move, didn't even try to kiss me. Could he just be trying to take things slow or just isn't interested?
