When is the first time you heard about this case? Was it last week?
How long did this man go without knowing this, two weeks?
It could be she was ashamed of being an exotic dancer. While the money is very good, and she can make her way without working really long hours, it's a job that many parents would (rightfully so) frown upon. If she talked about the attack, she would also have to let her parents know about the dancing.
Someone very dear to me was the victim of date rape at age 17. Her parents, who are super-protective, did everything right: they called the home where the party was being held and spoke to the parents, dropped her off and picked her up, met the young man and spoke to him, etc., etc. He still dropped a mickey in her drink and raped her.
It took her 6 weeks to tell her parents what happened, when she became suicidal.
Don't judge based on that; rape impacts everyone differently.
