"Indeed, it is the covenantal commitment that enables married people to become people who love each other. Only with time do we really learn who the other person is and come to love the person for him- or herself and not just for the feelings and experiences they give us. Only with time do we learn the particular needs of our spouse and how to meet them. Eventually all this leads to wells of memory and depths of feeling and enjoyment of the other person that frames and enhances the still crucial episodes of romantic, sexual passion in your married life."
