If you're moving in to 'test' the relationship, you're probably not so confident in it.
A 2009 study led by researchers at the University of Denver found that most couples moved in for other reasons besides test-driving their relationship before marriage.
But couples who did report testing the relationship were more likely to experience a number of negative emotions. For example, among testers, men scored higher on measures of depression and anxiety, and women scored higher on measures of abandonment anxiety. Both groups were less confident in the relationship.
In a recent Psychology Today column, one of the study's authors explains what these findings might mean:
"It seems to us that many people who think about testing their relationship by cohabiting already know, on some level, what the grade of that test may be; they are hoping that the answer looks better over time."
Contrary to popular belief, cheating isn't necessarily more common among high-earning couples. The link between income and infidelity is more nuanced than that.
Recent research from the University of Connecticut suggests that a person who is economically dependent on their spouse is more likely to be unfaithful — and that's especially true for a man who relies financially on a woman.
Interestingly, when women are the breadwinners, they're less likely to cheat. When men are the breadwinners, they're more likely to cheat.
