Is he crushing on me?:\

OK so there's this boy(I'm not going 2 say his name!) he's in my 3'rd period which is science.
Last Thursday..when Rustam went to my 1'st period(which is math)with some other 5 kids,to a test.So I was asking my math teacher a question.Then she answered my question so I was walking back to my seat.And then the boy sees me.And tries 2 make eye contact with ME!
Not only that!
But then at lunch time.I was sitting next to my friends.So then I see that same boy..AND I CATCH HIM STARING AT ME!.Then the boy smiles at me then quickly looks away,and starts talking to his friends.So then I'm talking to my friends again.
Then,one of my friends said"OK THAT BOY IS STILL STARING AT U!".I didn't believe her.So I look at that boy again to see if he was still staring at,AND MY FRIEND WAS RIGHT!
THAT BOY WAS STILL STARING AT ME! And again he smiles at me quickly looks away and starts talking to his friends.
That boy always tries 2 make eye contact with me!EVERYTIME HE SEES ME!
He always tries to act funny around me...because he always looks at me to see if I'm laughing or not.And if I'AM SMILING!He smiles too.
So what do u people think?Some of my friends thinks he's crushing on me....But I want to know what SOME OTHER people think.
So just answer my question:"Is he crushing on me?"
(p.s I asked this on Forum too.)
