She might actually be a decent girl in a fucked up situation. I found out one of my roomates was a hooker a few years ago-- I never would have guessed. She's pretty, sweet, and funny with a great laugh. She's doing better now, but she's been through some tough times. They're all human beings, and though she may be a liar and a manipulator, it's probably because she doesn't know any other way to survive.
