Crushing on a guy

So I really like this guy and I've pretty much tried everything, I've talked to him in class more and more often and I DMed him and I got his snapchat then tried chatting w him but when he replied it seemed like he didn't want me talking to him.. I guess he just isn't interested bc if he was, he would be reciprocating the communication or at least trying to talk to me too. I shouldn't have to be the one working for him to notice me.. if he actually liked me he would be the one trying to get ahold of me. And sure he's somewhat shown signs of interest at times but when it comes down to it he seems like he just isn't interested so idk what to do.. just like give up and wait to find a guy that actually makes an effort to talk to me? Or keep trying bc he's just super shy and doesn't know how to talk to girls??
