You are being taken advantage of, and you know it. My guess is that you also know what you should do about it, even if you're not ready to admit it. If you allow her to continue to behave this way, it's on you. She probably moved in with you for some sort of perceived freedom - the problem is, it's still your house, your rules. Living with someone, be it parents, siblings, roommates or significant others demands that you treat them with respect. She needs to learn that. The only way she will is if you make a big deal out of this, even to the point of telling her to move out.

Good luck, I know it's not easy.
