This last topic couples learn about in premarital counseling is conflict resolution. You also could call it the art of fighting fair.
Every couple has disagreements and conflicts, and most of them will come up again and again throughout a relationship.
Some of these disagreements will be over little things. He can’t seem to find the laundry basket. She apparently doesn’t know how to put gas in the car.
Or they could be over big things. He can’t stick to an agreed-upon budget. She spends too much time with her mother.
