NEED A RESPONSE PLEASE: Does he still have feelings for me?

So about 2 years ago I met this guy who I really liked and he also liked me back, from what his friends told me anyway, even though he never actually admitted it himself. We stopped being friends for some reason and then he started to spread rumours about me in school. I would try to let them not get to me as they were only rumours (this was about 2 years ago). And now, present day, I've moved on from him and everytime I see him he keeps staring at me, no one else, but me. Even though he might be with his friends, he still looks at me. Everytime I look at him he's there just staring at me and laughing at me sometimes. My friends even point it out to me. The odd thing is that he's the only one who stares at me constantly. The question is does that mean that he still has feelings for me or does it just mean that he's trying to annoy me? Or does it mean something else?
