Im losing my friend , which I already lost.?

My name,is tyye and I had a friend named Pierre. Me and Pierre were close friends and we always talked. We met last year September. But know,me and hom are,not friends anymore and he's acting like a jerk and acting like he is to cool. I asked him why aren't we friends and he said because i just don't want to be you're friend without giving a reason why. HATER !!! Some,people in my school don't like me and some don't even know my name . What should I do?
