She didn't call him out for a liar even though she knew he was. There was simply no way that a man like him would be able to change his ways so drastically just because a witch asked him to. No, he would do it again. The next time, because she knew there would be a next time, he had her naked, he would ask the same question. It was a power move for him, likely the only way he could feel in control of the situation. Either she would have to swallow her disgust to lie to him that her body belonged to him or she would have to come up with a different plan. She was hoping to find one where she didn't have to touch the man again.
