if you can't say it yourself to him that he makes you uncomfortable, tell your friends and together, tell him to please stop burdening you with his feelings.
if you don't have friends like that, talk to a teacher or counselor.
if you don't have reliable teachers or counselors, tell your parents
if none of the above work, act like you are having a meltdown next time he vent flirts with you, nothing like crazy to ward crazy away
