Major factors behind broken marriages revealed

There are several reasons that lead to a broken marriage and this can be prevented if couples take preventive steps to avoid split.

According to a Norwegian study released in August 2012, the divorce rate among couples who divvy up household chores is about 50 percent higher than those where only the wife handles the chores, the Huffington Post reported.

Researchers said that higher divorce rate has more to do with "modern" values and attitudes-such as viewing marriage as less sacred-rather than a cause-and-effect relationship.

Swedish scientists have revealed in a study that a specific gene might explain why some women have a hard time committing, or staying committed should they get married.

Researchers found that women who possessed a variation of the oxytocin receptor gene known as A-allele were less likely to get married, as they have a difficulty in bonding with others.

The scientists said that those who had the gene and got married were 50 percent more likely to report "marital crisis or threat of divorce."

A close relationship with your in-laws may change your divorce odds.

A 26-year longitudinal study conducted by the University of Michigan found that when a husband reported having a close relationship with his wife's parents, the couple's risk of getting a divorce decreased by 20 percent.

But, when a wife reported having a close relationship with her husband's parents, the couple's divorce risk increased by 20 percent.
