I would have to agree with some of the other people. Maybe having you all as support and being able to go out with sisters who care about her (instead of sleeping with guys who don't) may just stop her behavior... then again maybe not... If you are REALLY worried that this girl is very catty and will not be tamed by having a support system.. then don't give her the bid.. but if you could see having some caring woman around her helping her out.. take a chance... it could be a turning point for her.
