I have seen many women in my practice who keep interrogating their husbands about this 'other woman.' Their husbands become frustrated and assure their wives that the other woman meant nothing to them and that their wives mean everything to them.
Instead of wanting to leave her and end your marriage you've decided that the whole affair was a big mistake. But in your heart you know that the affair isn't over. You're not sure how to end it. And you're scared.
