If you're on this path she spends massive amounts of time flirting with you. Its not like she doesn't want to do pervy stuff with the MC, she just has hang ups about it. She likes you and trusts you. A mature person doesn't assign the blame of their trauma on every person that follows in their life.
Besides, if the writer decides she's fine with it, she's fine with it. By that measure why is is okay if him and his blonde bestie fuck around? She's been assaulted over and over by this point. She has very real hang ups about it. She still gets very handsy with the MC. Not every female is going to react the same to everything. Especially if the dev doesn't write her that way. Maybe don't expect everyone to feel the way you feel about a situation.
