Why didn't she just get out of there as soon as she felt uncomfortable? many people explicitly or implicitly asked.
It's a rich question, and there are plenty of possible answers. But if you're asking in good faith, if you really want to think through why someone might have acted as she did, the most important one is this: Women are enculturated to be uncomfortable most of the time. And to ignore their discomfort.
This is so baked into our society I feel like we forget it's there.
