One of the key elements to fighting well is being able to read your partner, to know in any given moment what he or she is feeling, thinking, and intending. We may not be consciously aware when something is amiss, but we often can feel it in our bodies. We just don’t quite feel right somehow. Probably the most reliable way to read a partner, however, is to use our visual acuity. When we look at our partner, our eyes rapidly and continuously take in information: moistness in his or her eyes, a slight flinch, the hint of a smile, a curling of the lips.
