Sounds to me like you have given every advise possible, however insisting on keeping up with the adivse you will surely push her away. All you can do is be her friend, show your love and hope she turns things around. It is everyone's choice weather or not to abide by god's laws, therefore it is everyone's indiviual judgement that they face. But for you i'd say watch to whom you associate with, for you will surely be accused based on someone elses actions.
