Women who have low intimacy levels at varsity may be more likely to divorce later in life, according to a study in Personal Relationships.

When researchers at the University of Massachusetts at Amherst tracked down 167 people who had taken a psychological test 34 years earlier, they found the correlation – but only among women. Women tend to take a more active role than men in maintaining and working at a couple’s closeness, so a relationship in which the woman shows less intimacy may be more likely to falter, says study author Dr Mark Weinberger.
