To de-friend or forgive?

i'm so pissed at my sort of ex-friend right now. she went emo like, 6 months back [and i'm sorry, but i think emo is bullshit anyways. but that's another story.] so i changed my name on facebook, for FUN. she posted something about how people change their name on facebook are desperate for attention [in her opinion.] well, i told her that if she wanted to insult me, to do it to my face. she gave me a bullshit answer. i told her that if she wants to talk about desperate for attention, talk about her going emo. she posted something about me being a bigot. i pretty much think that's the most offensive thing she could say. she didn't say my name, but who else could she be talking about? i'm very tolerant of other people. i'm just sick of her ****. thanks for your help.
