How can husband and wife keep a loving marriage?
Stay faithful and be friends
When each partner keeps away from others, each becomes attached to the other and a loving life follows. Live as friends in marriage, welcoming each other with warmth.
If the woman married to you has no contact with any other man, she will become attached to you. If you have no contact with any other woman, you will become attached to your wife.
