As well as the 'obvious' markers/indicators that your marriage could be heading for divorce, economists in the US have undertaken research which suggests that when a couple are not in touch with how their spouse is feeling, the marriage is more likely to end in divorce.
The advice at the end of the article is perhaps the biggest 'take home message.' Being honest with each other about feelings, concerns and desires is the best way to start identifying problems and the same could be said if the marriage unfortunately does breakdown. Communication, whether the marriage has broken down or not, is key to resolving disputes or issues between spouses. It is for this reason that the court's place an emphasis on mediation and encourage spouses to sit down together and discuss their issues in an effort to try and reach an amicable solution or compromise.
Decades of relationship research has linked specific negative behaviours — from contempt and defensiveness to a failure to resolve conflicts quickly and openly — with divorce. And psychologists have long observed that people in happy relationships are less tempted by other potential partners, although it's unclear whether it's satisfaction that makes people more committed or that people who are already more committed are therefore more satisfied. But this is one of the first studies to suggest that misjudging your partner's satisfaction with a relationship could make you more likely to split up several years down the road.
