A new study by Cornell University and Facebook suggest the social network can predict how healthy your relationship is.
According to CNN, researchers got insight from more that a million Facebook users.
The yardstick used to measure a relationship was something the researchers called dispersion. The term relates to how well a couple's mutual friends are connected.
Researchers found that a couple with a "low dispersion" rate, meaning the couple's friends are well connected on the site, are 50% more likely to end the relationship over the next two months.
They compared that to couples who have a "high dispersion" rate, when the couple's friends are connected to different groups of people.
In simple terms, the study suggests people in the healthiest relationships have their own lives and friends. The findings will be presented at a conference on social computing in February.
