Numerous studies show that once we become attached to someone, the two of us form one physiological unit. Our partner regulates our blood pressure, our heart rate, our breathing, and the levels of hormones in our blood. We are no longer separate entities. The emphasis on differentiation that is held by most of today’s popular psychology approaches
