He loves me....He loves me not....?

I have been friends with this boy I know for almost 3 years now. At the start he was all "oh I wanna be 'friends' with you" and I wasn't sure how to react to stuff like that because I'm a red-head and nobody usually asks me stuff like that because I'm not exactly that pretty! He asked me to meet him and I said no (because my friend talked me to saying so) and now he's always mocking me and teasing me, but I still really like him. And now it's really bad because he turns out to be one of my best friend's Maries cousin and they tell each other almost everything!!!!!!!!!!!!:(
