why is a acting weird

i go to colledge and i like this guy these are the signs he DID before

1- always stare
2- when i wasnt looking he will look
3- when i walk past him he will look at the floor and doesnt even look at me
4- i always catch him looking.
5- he asked my friend if i have facebook but i dont
6- we never talk much just hi and bye
7- he suddenley came up to me and say hey.


and lately he is trying to avoid me whenever he knows im there he will pretend to look somewhere else.

and when i wasnt looking i feel he is still looking.

- i didnt say anything bad to him and my friend didnt say things too him.

- i didnt make him upset


so im thinking is he trying not to like me because he thinks it wont happen

or

he completly hates me out of blue.

Maybe he's losing interest. Talk to him, smile, ask him to hang out if you like him.

It sounds like he's given up on trying to make something happen.
