I think she thinks her husband has slept around behind her back. Bill tells her how sorry he is, that he's stressed, on the road a lot, how much she means to him. They make up, shit is squashed. When the accusations started to come about, he probably told her that its all bullshit, that he did sleep around with other people, but that they're trying to hurt him now, trying to get at his money, that their jealous that chose her over them.
