Does he like me?

Ok I met this guy at school, we are both in 3rd year university. I dont know if he likes me or not.
This is what he did to me:
1) always wanted to be in the same class with me
2) ask me if i want him to call me in the morning so i wont miss a class
3) sometimes he waits for me outside my class and then have lunch together
4) he asks me what color I like...I said purple, he then gave me a purple pen
5) always make fun of me: follow what I just said, laugh at almost eveything I said
6) sometimes hugme from the side but didnt say anything
7) after lunch he always come to my class even though he isnt in that class
8) our friend asks me if he's my bf, i ask him if he wanna know what she asks
me...he said he knew it, how can he know?
9) our friends always make fun of me but only when he's not there
I wanna know if he likes me or not...if so why didnt he tell me. One thing I
am not happy about is he always did something speical to me but then he
didnt say or do anything after...I'm so confused.
Thank you guys for answering.
