I really struggled with this at school, girls didn't like me much and I could never work out why, looking back it is because I was very pretty (I'm not syaing I'm better than anyone else or the most beautiful woman in the world btw). I did have some very good girlfriends but was never accepted into groups of girls. I found this a lot throughout my life and it used to really get me down.
I have noticed it reared it's head at the school gates again, it has taken me a good few years to be accepted by the other mums, being shy doesn't help either.
AIBU to think this is something that often women (obvioulsy not all women!) don't like other women who they think are pretty??
