Everything he's done since the day that they met, he just wants her happy, and out of this mess. She doesn't want to disappoint, but can't seem to run away from the lies, with the truth like a gun, held to her head by her own shaking hand.
What would bring her out of this is no simple man. The only way out, the only light she can see, is the one that will **** her, but would set her soul free.
She can't -- she wont -- he doesn't deserve that pain. So instead she hides, forgets her own name. Better to please him and make him think he fixed her Than to tell him the truth, that nothing can change it for sure.
