What should I do to get him?

Stay the way as you are and don't ever try to please him for something that might embar yourself. Just keep in touch with him. Make a conversation that would make him smile and be happy always. You may try to make a trick story. Or do some questions in a joke way, like saying: "if an ugly woman would approach you, what will you do?" (try to smile too when you ask such question). or you may say, "if one day I would meet a man that will tend to like me, what advise could you give me?" or "what if there's a man who likes me but I don't him, what should I do?" value your friendship for the meantime because who knows he is only studying about yourself. in some other points, love can be developed from a mutual feeling. so it could his style either. as long as he is keeping in touch with you, and all what you said about your company with him, there is a big possibility that both of you would come up in one feeling. have trust in your feelings and show him the care you do as always.
