If couples would remember the following rule, it would help. Every time you put a smile on the face of your spouse, give yourself a point. The one with the most points wins.
People need to be involved with their spouses interests. Even if it doesn’t interest you personally, if it interests your spouse, try to be a part of it in some way. This goes for their friends, family, hobbies, etc. When you ignore or turn up your nose at something that is dear to your spouse, you are setting yourself up for a big problem.
One further thing is that men need to learn that women are looking more for emotional closeness than physical closeness. Women need to learn that men will always be interested in physical appearance, etc. So both need to do what pleases the other. Initially, men worship their wives just by virtue of the fact that they are female. They will do anything for them. But as soon as a woman lets herself down and starts whining about something trivial, all the attraction can go down the drain in one minute, and can be lost for good. Women need to understand that men want to view them as goddesses. This means that women must appreciate the beauty Hashem has endowed her with. A man thinks that such amazing female beauty is mesmerizing. But women think of themselves as just humans like everyone else. If a woman might get upset over some trivial detail like her husband brought home the wrong color napkins, the man can’t figure it out. He thinks, she is a millionaire because of her natural gifts, and now she is worrying about a few cents? Why doesn’t she appreciate who she is and what she has that everybody thought she was the best looking girl in the country? She is acting like an immature spoiled child, and what happened to the fact I thought I was married to a godess? I was in an illusion. Once the magic goes out the window, the entire marriage may follow.
Women need to use their inborn beauty and kindness to advantage and keep the magic going their entire lives. They need to not fall into the trap of being human. As long as their husbands think they are godesses, they will do anything to please them. Of course the husband must be a baal midos, but he naturally will act his best if he is enthralled with his wife. When someone stops liking somebody, and you lecture him on trying to act like a baal midos, it often doesn’t work, since deep down he is unhappy with the person. Better to keep the magic of dating going your whole life.
