Om Swami
How should I behave when I fight with my husband or wife?
Fight, but leave room to make up
Even in a quarrel, leave room to become friends again so you need not feel ashamed later. The more a person has fallen from their own state and understanding, the more they fight as if they will never see the other person again. That kind of fight is possible only between husband and wife.
Be enemies fully if you must, but leave enough room that if you become friends again someday, you need not feel ashamed.
