Why doesn't he make a move?

i think my friend and I have developed something more we hang out everyday for hours he tries to be on good terms with my best friend he stares at me when we are studying always tries to make me smile gives me messages offers to help me with whatever I need I'm not really sure if he likes me... but the last couple of time we hung out alone he insisted on paying so I'm thinking that's a date? anyway he has done significantly more then I have, and he knows it, but yet he still hasn't made a move we haven't even hugged, except for an awkward hug once, since we meet after summer. I'm not really sure what to think so I just wanted your advice.
