Dude, deck the snotty little brat. She totally can't be worth your time. No one should be treated like an asshole when they've always gone out of their way for another person. If she can't at least talk to you, then it's her loss, because you sound like a good friend, and it's her problem if she can't recognize the good form the bad.
