Theres this guyy I really likee and have no idea if I should tell him and how?

You need to try and get to know him as a friend first :) Become friendly withhim and then you'll find out whether he likes you or not, and indeed whether you do really like him :) There's no point asking ihm straight out if you don't really know him, but you can if you really wanted to :) best of luck :) x
