After all, abusers often say that they're doing what they do as a reward or as a punishment, even if they are horribly inconsistent. The victim gets these double reinforcements, and starts trying to please the narcissist. From not going out of their home, to wearing smarter clothes, to waiting before she answers him back... she treads on thin ice, so as not to fall in. This, she hopes, will stop him from coming back home drunk, from hitting her.
