It look like she enemy within.
Actually she filled case with the help of her parents, she is just staying with you to get inside information and pack your valuables.
Never trust a women she can stab you on your back anytime. They can change their Statement / tone within fraction of time. she will agree with your every word but as soon as they reach Police / court they can change as per they planned.
take all your valuables without her notice.
get xerox copies of all her documents, and also phone numbers / address.
tell her to clear the case or withdraw or whatever, if she wanted to stay with you.
If she file DV on you, then you have to provide her accomodation and maintenance
