I have seen many of these kinds of marriages...unfortunately these kids don't learn to communicate fully with members of the opposite sex. The resulting marriage is built around escapism. The men either get heavily into golf or spend most of their time in front of the TV watching John Wayne Movies or NASCAR, and the women drink tea with their friends from the garden club.
IMHO, sheltering an individual from dating doesn't help them to trust themselves or to become a rational adult.
That's the point. The Big Book has all of the store-bought answers we need. Any problems in a marriage are a result of not enough Jesus, pure and simple.
The non-dating marriages have been incredibly successful. The kids learn how to communicate far better because they are not constantly trying to get into her pants or keep him out of her pants. No sexual distractions so they can actually get to know each other. It's amazing how interesting a girl can be once you get your mind out of her knickers.
