How Facebook can ruin your relationship: 'Site induced jealousy' increases risk of divorce and break-up Excessive Facebook use increases risk of cheating, break-up and divorce People jealously monitor their partner's activities and reconnect with their ex The younger the relationship, the greater the risk of Facebook problems Facebook and social networking sites may be good for our social lives, but they can cause havoc in our romantic relationships, according to a new study. From emotional and physical cheating to break-up and divorce, researchers found 'Facebook-induced jealousy' significantly increased the risks for couples of all ages. Research found that conflict was much more likely to occur when the website was used excessively, because some people tended to jealously monitor their partner's activity or even to reconnect with ex-partners. From emotional and physical cheating to break-up and divorce, researchers found 'Facebook-induced jealousy' significantly increased the risks for couples of all ages The study, led by Dr Russell Clayton, of the University of Missouri, U.S., surveyed Facebook users aged between 18 and 82, asking them how much they used the social network and how often they had bust-ups with their partners - past or present - that had been ignited by the site. Dr Clayton said: "Previous research has shown that the more a person in a romantic relationship uses Facebook, the more likely they are to monitor their partner's Facebook activity more stringently, which can lead to feelings of jealousy. Facebook-induced jealousy may lead to arguments concerning past partners. Also, our study found that excessive Facebook users are more likely to connect or reconnect with other Facebook users, including previous partners, which may lead to emotional and physical cheating. According to the study, published in the Journal of Cyberpsychology, Behavior and Social Networking, couples who are just starting out should consider staying away from the site. Dr Clayton explained: "The findings held only for couples who had been in relationships of three years or less. Conflict is much more likely to occur when the website is used excessively, because some people tended to jealously monitor their partner's activity or even to reconnect with ex-partners This suggests that Facebook may be a threat to relationships that are not fully matured. On the other hand, participants who have been in relationships for longer than three years may not use Facebook as often, or may have more matured relationships, and therefore Facebook use may not be a threat or concern. Although Facebook is a great way to learn about someone, excessive Facebook use may be damaging to newer romantic relationships. Cutting back to moderate, healthy levels of Facebook usage could help reduce conflict, particularly for newer couples who are still learning about each other.
