ugh. I agree with you completely! If someone had raped me or even tried to molest me, I’d never be alone with him again. It does not make sense!
It was, by her own admission, a "transactional relationship", meaning she was having sex with him in the expectation that he would do something for her in return, presumably help her get a promotion or better assignments.
When he failed to deliver what she expected, then she retroactively deemed it "rape".
