A fight to the finish is what finishes a marriage. That's because over the course of married life, people supply their spouses with precisely what's required to finish them off. The question is not who can win, because anyone can win if they're willing to go far enough--if they're willing to win at the cost of love and respect. The question is who can resist the temptation of winning. If your marriage is healthy, you are fighting to restore the balance of power. You are fighting to find out what's worth fighting for...and you will find out that what you are fighting for is the marriage itself. What matters most to a marriage is forgiveness, and forgiveness doesn't come for free. You have to fight for it.
