How should I act to this situation ?

[Coqueta.]

Ive had a crush on this guy at my college who plays basketball , well , I followed him and he followed me back so , the trending topic on twitter was "mentionsomebodysexy" so, I mentioned him to let him know that I thought that he was attractive ! After that, we start saying hi and then he asked for a hug so, I gave him one. SO! After that hug, things went downhill..I tweeted him saying "I hope your okay" and he never respond back. Then I messaged him today and told him that I hope he has a great thanksgiving break and he didn't respond back but he'll tweet other people . I don't know how to handle this situation because I really want to get to know him but I feel like he's not getting the hint that I want to talk to him...What should I do? By him not responding back...should I leave him alone and still be speak when I see him in person?
Please don't be rude...
