well as a guy i say
if you are close friends (assuming its not in a public place like school) just kiss him
trust me if you kiss him he wont resist and it can be a way to find out if he likes you
if he kisses you back or makes it a more affectionate kiss then he probably has at least some feelings for you. If he doesn't kiss you back but doesn't pull away, just kinda sitting there shocked then he might still like you but never thought you liked him. If he pules back, then he probably either isn't ready or doesn't like you like that.
