Learn to Fight Right: Remember You're a Couple

We know this is a tall order, but if you can express positive emotions during an argument, you'll have a more satisfying relationship two or three years down the road, according to a study published in the Journal of Marriage and Family.

"When couples are able to communicate closeness, affection (for example, a touch on the arm or the cheek), and even humor in the midst of an argument, the impact of harsher words is diminished," Karney says.

"Positive interactions say that you still like and love each other, and you're committed to the relationship even in the worst of times."
