This is a poor decision on your part.
Many people are utterly clueless. You won't get what you want in life by hanging back and wishing and hoping someone will catch the hints you're dropping or will read your mind.
Spoiler alert: if he's like over 95% of all humans, then he won't.
Ask him out for coffee and tell him you'd like your next time out together to be a real date. And see what he says. He may feel the same way and think you aren't into him. You will never know unless you make things crystal clear.
Nothing ventured, nothing gained.
