I think you should prolly try to work it out again, just so that you don't have an enemy, ya know? I don't think it'd be a good idea to get back to bein' bestfriends or even just friends if she's two-faced and all that other stuff. I don't really see what you did wrong, and I mean, you tried to apologize, right? Well... I guess, all I can say is maybe try again and see what happens. There's no harm in trying to reconcile with someone who used to be your good friend. In the end, though, its really up to you and whether you really wanna put up with her or not and whether your relationship is important enough to you. Umm... but yeah.
maybe u guys dont have to be best friends but u can be just friends but if that doesnt work out then dont be friends but dont hate and be mean to each other because that just gets u nowhere[outcast12345]
i think you should try to be friends with her again but sometimes its better to move on and find new friends cause it mite be hard to trust her the way you use to and stuff.
