My dear Jil, from the content of your mail I think there are two major things you need to focus on: ambience and attractiveness. If you get those two things right your marriage should be okay. Let me break them down.
If there’s nothing you learn at all, it is the fact that men are visual. Extremely visual! And if Jack can’t change the essential nature of a woman, you can’t change a man’s either. He is visual!
