Relationships- why do some of us stray

For some people, a wandering eye is a matter of personality.


In a man – woman relationship an individual's character traits are the most telling sign of whether they will be unfaithful to their partner.


Swinburne University psychologist Julie Fricker has found that people who were uncomfortable with intimacy and uninterested in commitment are the ones most likely to stray.


Theirs are behaviour she put down to "avoidant attachment" relationship-types, people who also believed there were alternatives to their relationship.


In an unexpected twist, those who had heavily invested their money, time or experience in a marriage relationship tend to be unfaithful, because the cost of making a clean break is too high.
