Learn to fight right. Couples can’t think straight when they become embroiled in a heated argument. The happiest married couples know how to argue productively. Take a breather, physically walking out of the room for at least 15 minutes, or change the subject completely until you can come back to the point of contention calmly. Backing away from an argument isn’t “losing.” In the end, you both win by being able to find common ground.
