Take the initiative. Like the Shulamite, do not be afraid to make the first move.
Humble your pride. Remember how much you love your spouse and that petty resentment is a dead-end street.
Acknowledge that you were hurt. Yes, it is difficult to live with the pain, but no relationship is perfect. Do something about it.
Believe that God can heal your marriage. Miracles occur every day.
Remember, one of you can stop the deterioration; both of you can reverse the damage. It is possible to make your marriage as exciting as it was when it began, if you will go back to doing what you did before things grew cold.
