Should I give up yet?

not to be cocky, but I normally don't have a problem getting guys, and I used to be kind of a bitch about it, and would shut down guys pretty hard who tried to get to know me romantically. so last winter this really nice guy started to like me but he was a little pudgy and didn't play any varsity sports so I shut him down pretty hard. however, I realized I had made a huge mistake 3 months later and I started liking him and I've liked him for almost a year now. problem is: I'm afraid to tell him because I'm used to guys approaching me. he stares at me in class pretty consistently, and I always hold the gaze, smile, and look away like I'm supposed to- thought he might be into me, but last night he hooked up with some girl on the dance floor at a formal at our school. should I give up?
