]I have liked this guy from a class at my school for this year and sometimes he seems really interested but I didn't see him for a few weeks due to him going on holiday.
I saw him in class and then he wasn't really friendly like usual...I don't know why.
He only said hello just normally and then started talking friendly to other people around me.

I don't know why now hes starting to ignore me....or maybe its me...help?
