Ok so youre scared. So you can sit there and not find out. Or you can be brave, ask...And be prepared for rejection, if he does. The only way to find out is to face your fear. You can play it off as friends for longer, but what if your missing out on a relationship? He can say he doesnt like you like that so you can remain friends right? Why dont you ask him to the movies or maybe a dinner or out on some kind of date and see how he responds. Then take it from there. But you cant be upset if you get rejected. At least you tried right?
