This is annoying the hell out of me, please someone tell me

DOES HE LIKE ME
So there’s this guy I have a crush on and he turns around and looks at me whilst walking but I really think it’s because I stare at him 24/7 lol. Anyway he always avoids eye contact with me whenever I look at him straight. One time he turned around and looked at me twice whilst walking home. And then he stood near his regular bus stop and I turned around and looked at him before I left and he made eye contact with me for 1 second and quickly looked somewhere else smiling and he was so embarrassed trying to hide his smile.

Then I remember I got put into a group project with him and a few other girls and he got so shy. Then later I smiled to myself when I saw him and he sits right behind me for that subject so then he was smiling and looking at me when I wasn’t looking. I turned around to look at the time and that’s when i realised he was looking at me because my back is faced to him and he quickly looked somewhere else smiling right after I looked at him.

I caught him staring at me in the exam hall and he didn’t look away. We did a class test once and I secretly caught him leaning down to see my face then he quickly looked elsewhere

The thing is, is he smiling to himself because he genuinely likes me or does he just like the attention that he’s getting

In my opinion it’s really hard to tell, please help me
2 people told me he likes you and one person said that they think he just clocked that I like him, I hope the second answer is not the case
