Ok, so you screwed up by having dinner with another woman. As others have said, you and your wife need to sort this whole thing out together, or to paraphrase Ben Franklin, you most assuredly will do so separately. I would strongly suggest marriage counseling. The goal is NOT to persuade your wife to accept your cross dressing, but for the two of you to reach an agreement on the future course of your marriage...whether it is towards dissolution or continuation. If it is to be the latter, then there will have to be some sort of accommodation of your cross dressing, because it is highly unlikely that you will ever be able or even willing to suppress the desire.
