Is it normal? & how do I deal or solve it?

So I have known Jenny* since kindergarten so far we have been best friends, but since middle school i've been noticing I'm starting to secretly hate her. To set the record straight I'm not jealous. I give the details about her behaviour. She dates boys constantly, is oblivious to music, very unintelligent, and is two faced. Not so long ago she had sexual relations with a boy she only knew for a week but she got pissed because I was talking to her ex(we were talking about a homework assignment) she went to my locker and screamed "you didn't ask me if you could talk to him". She got over it quickly but has been bitchy ever since. Plus more recently she has discovered daft punk, not only does she find out about them she claims to be their biggest fan ever and always will be. I f**king want to claw her ears out. This sh*t always happens when she finds someone "new" shes their groupie. I just asking is it normal that genuinely hate my "best friend"?
