On average the most unhappy person in a marriage is the woman. Why? Neuroticism: greater sensitivity to negative emotions. Men worry about a few big things. Women about many small things. And between empathizing over systematizing, neuroticism over calm, magical thinking over realism, and demand for stimulation (consumption) over capitalization, its no wonder. So women with less than four children to consume those intuitions rationally (their purpose) let those emotions destroy a family rather than make it. Hence divorce rates.
