DEUT1334 During the first year of marriage, a newly married man must make special efforts to make his wife happy. Hashem wants the world that He created to be inhabited by good, moral people born of legal marriages, not promiscuity. For this reason, He commands that when a man takes a wife, he must remain at home with her for their entire first year of marriage. He becomes accustomed to his wife and well acquainted with her mannerisms, personality and total being. As a result, all other women will be to him as strangers, for their behavior and personalities are very different from his wife's. Because of this year with his bride, he will always stay away from other women, and keep his thoughts on his designated mate--his wife. Thereby, the children that they will have will be upright and good, and the world will be settled by the type of people for whom it was created.
