Jackie?
Jackie is not a whore. She is addicted to heroin. When the abstinence hits in, her brain can't fight back, and the only thing she sees in her head is possibilities to get her heroin so she can get away from the sickness for a while. The abstinence comes back fast and is terrible. Of course "she could just stop using the heroin" but you dont know how feels to be addicted like this. And when her "boyfriend" dies, yes its whore-like to just take the money and go away. But you would do that too if you were in the same state as Jackie.
