Real love knows no bounds.
For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. So they are no longer two but one flesh (Mark 10:68).
In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church (Ephesians 5:2829).
