drama between sisters

[AlethiaSi]

i freaking feel like the drama never ends with me- its so rediculous basically without going into too much detail- one of my "sisters" hooked up with this guy who he and i have been dating/seeing each other for over 8 months... she was told repeatedly by several people not to hook up with him b/c he and i were still on and off- and she's known our history- but she did it anyway- (plus i've already talked to him about it- and he verified it too) i feel so hurt and betrayed- and this is not the first time she's done this to one of us either... she's always a trouble maker- and i didn't even want her in the sorority- but she is- and so i was always nice to her- just not that close.... i'm so upset and mad at her.....

since the semester is over and its the summer i just am letting this get to me.... i've already talked to her about it- and she knows i'm really mad.... i don't want to be around her (and she deliberately chose to live in the room next to mine in the house too!! grrr) can i do anything- should i just ignore her? my sisters are all really upset and mad at her too- they don't want to be around her and they don't like her either b/c of this and many other situations oh- and she was a problem pledge too!.... has anyone else dealt with a situation like this?
