You got rid of her later by messing up her reputation and using various school regulations to make sure she didn't keep coming back to harass you, right? I think I remember you saying smthg to that effect.
I believe you. Like wtf is a guy supposed to do when a girl overpowers him and holds him down and fucks him? Sure he could beat her bloody. But he could spend the next 5 years or so in jail for it. And the student loan gestapo don't give a rat's ass if you go to jail for using violence to avoid rape. They add the interest whether your life sux or not.
You did the only thing you could have done. Congratulations on salvaging your career despite being treated like a fuck toy ;)
