Friend Or Foe

I'm at my friend's house party. My best friend is of course here too. We we all have that best friend.. the one that is sorta the mothering type. The friend that my parents love and I can always count on her to look out for me no matter what.
Anyhow, I have a few best friends. This best friend formentioned (Jenn), was like a sister to one of my other best friends, Chelsea. In the past year they have grown apart, fought, and now (in the past few weeks) have forgiven each other and become friends again. I am in my friends room blogging while others are party because A) Jenn and Jordan just ripped Chelsea a new one (though she is not present) and B) I'm really drunk.
Chelsea recently forgave Jenn for being a really really bad friend. Chelsea lives two hours away and so she's never here to hear Jenn amd Jordan bash her. Jenn had been crying every weekend since last August because she missed Chelsea being her friend. This is why I'm mad: She misses Chelsea, but she will bash her like only an enemy would at parties. I am so mad because Jenn is and should be greatful that Chelsea forgave her but she just called Chelsea a whore and volunteered information about Chelsea losing her virginity TO THE WHOLE PARTY. She just forgave you and this is how you act?! What kind of friend are you?!
When she's sober she's okay, but when she's drunk I hate her. I'm so glad I'm moving to Colorado. Between now and then I don't know how I feel about her as a "best friend" anymore.
