“All couples have some irreconcilable differences. But when partners can’t find a way to accommodate these perpetual disagreements, the result is gridlock. When couples gridlock over issues, the image that comes to my mind is of two opposing fists. Neither can make any headway in getting the other to understand and respect their perspective, much less agree with it. As a result, they eventually view the partner as just plain selfish. Each becomes more deeply entrenched in his or her position, making compromise impossible.”
