How can I tell if he likes me?

I told this guy I go to college with that I like him, his response was 'I read your message I like it'. At college we get on great, he's sweet, funny and good looking. I wanna know how to ask him if he feels the same without him saying he doesn't know how he feels.. I really like him and have done for ages and now he knows we both know it wont be awkward, he starts conversations with me and uses smileys a lot.. dno if that makes sense but please help me lol thanks x
