Shit. I can't fathom how she ended up living with her parents and not you. I would think if she gets a diagnose you would be in a good position legally, even the breakdown should weigh in.

Stay strong, my advice for the girl remains the same.

AFAIK, Poland is pretty traditional and Catholic. Would it make a difference if you could make a case that you are "faithful" and she is "unfaithful and promiscuous"?
