Look at you, because you were discovered, you thought about how to explain it, but you didn't find it, so it passed. Isn't this stealing? With a friend like you, she lives under the same roof for eight generations. If I were her, I would break up, tell my tutor, complain and call the police, and I wouldn't miss a step! If I were you, I would take the initiative to withdraw the manuscript, lose money, apologize and leave her. Of course not.
