Why Don't People want to get to know me?

I moved around a lot in 3 years I went to 8 different schools.I always made friends on the first day, ever one liked me. Now that I moved to this new school it took me 1 week for 2 girls to be friends with me. It was toward the end of the school year 4 weeks till summer, but even when I started at school when their was 2 days left I still made friends. I'm funny I have a great personality. I think I'm pretty nice looking. Adults tell me I'm gorgeous but their adults in my family like aunts and cousins. So they don't count. One the first day the "popular" girls were total b*tches to me they were really rude and disrespectful. I wasn't mean to them when they called me names I just said " Wow you guys must like talking about me to get such a terrible impression about me by the way I'm not like that" then they just walked away. I just want to know why they don't like me without getting to know me.
