Of course you can.
And you'd better act, or you'll lose your shot.
Quit farting around and talk directly to him (not through an intermediary; these aren't the Paris peace talks) and ask him out. No big confessions of love. Just, John (or whatever his name is), let's get a coffee (or a soda, something without alcohol). Laugh, have a good time, just the 2 of you. At the end, tell him you had a good time (if you did), and then say, "Let's make next time a real date."
And see what happens.
Waiting around, wishing and hoping, have gotten you nowhere.
It's time to act.
