True love does not force itself on anyone, and it does not force change; it evokes growth. How? First, by accepting one's spouse as he or she is. When we marry, we do not sign up to change the other person; we just agree to love him as he is. The best thing a husband can do to change his wife, or vice-versa, is to change himself, to correct his own faults—in keeping with Christ's instructions to His followers.
We think of disloyalty in a marriage as being when one spouse commits adultery. The fact is, we can be disloyal and unfaithful just as thoroughly by putting business, or parents, or hobbies, or someone else before our spouse. That, too, is disloyalty. And anyone who is not ready to place his spouse ahead of career, ahead of parents, ahead of friends, ahead of recreation, is not ready for marriage—and such a marriage will fail. Marriage is for adults, not for children.
