Is it possible for a guy to like you if he never comes around or makes an effort to talk to you when he sees you by yourself?

Yeah,it's possible. He could be shy. However, its a huge waste of time and energy to worry about him. Go for the guy that's willing to let the world know he is interested in you. In time the other guy may realize he needs to speak up. When you come across a guy such as this, you make the first move and approach him..If it's him who you want..
