Nicki: I didn't marry for love. I married for the principle. Barb: I didn't. I tried. I don't know if I have a testimony for the principle. But I love you, I love our family more and more. Nicki: That frightens me. I don't know that a marriage based on love can go the distance. The secret holiness of the institution. The sanctity of marriage. Without it, it's just random couplings, with no purpose or sticktoitiveness. How will we survive the bad times on just love?
