Not sure if this is the right place for this question or whether it's even legal to talk about, but a girlfriend has asked me to ask people here. We have never been close to prostitution and our boyfriends have no clue either (honestly!) but anyway my friend is living with a girl about her own age, and it seems likely she's a prostitute. My friend's question is whether to confront her with this, to stop her from doing it, because this other girl is apparently catatonic with depression. But how to broach the subject, ask her straight out? Would she even stop doing it, given she has no other means of income?
