"I trust no one. You did not break me."
I don't claim to know what did or did not happen, but the above doesn't have to mean sexual assault. For all we know, it could be a bad breakup.
Maybe he made her think she was worth more to him than she was so that he could sleep with her (you know, like what happens a ton in college).
Maybe they were a thing, and then he dumped her when he realized he was getting a big payday. Maybe he made some promises he didn't keep. Maybe he was an asshole to her. Maybe it *was* a sexual assault. Lots of possibilities.
