I'm sure it's not sex.
Just out of pure curiousity, I did a quick search on the topic to see what other results show. There are tons of different polls and researches accomplished on common divorce reasons, and the just to throw a couple examples:
-------------------------------------------------
According to Los Angeles family instutute professor Paul Popnau, key divorce reasons are:
a) sexual incompatibility;
b) not having a common opinion on how to spend time;
c) financial issues;
d) mental, physical or emotional abnormalities.
A poll accomplished by GFK Roper (http://www.gfkamerica.com/) states other figures: "GFK Roper spoke to more than 1,500 people by telephone to discuss marriage and divorce issues with them. Slightly more than half of the respondents, 860, were women, and the rest were men. There is a margin or error of plus or minus 2.6 percent for the sample.
When looked at separately, men and women were divided on what they saw as the reasons for their divorces. Women overwhelmingly said they made the decision to divorce because of abuse issues with a response rate of 48 percent. But 23 percent of men said the reasons they divorced were based on money. Another 22 percent of men cited sex as the reason for the divorce.
In fact, sex as a reason for divorce was the most divergent response. It was high on the list for men, but very low on the list for women. Just 11 percent of women said sex was the reason they divorced.
Christie Lawrence, who hosts Pathways Life Management Seminars in Texas, said the divergence makes some sense because as women are feeling dissatisfaction with their relationships, they are less likely to want to have sex. Men might see the lack of sex as the problem, but it is likely something more complicated, Lawrence said. There is conflict and confusion between men and women regarding the definition of intimacy, she said."
-------------------------------------------------
Afterthought: naturally, the results of different polls are different, and the "weight" given to sexual issues differs as well. Although I would think that 22% naming sex as KEY reason for divorce is even more surprising than 49% saying it was one of the reasons...
Anyhow, this doesn't fall under the topic of the thread. If the situation interests you to that high extent, you can always run an investigation of different sources and come up with an opinion worth to be posted as a dedicated thread. Maybe even under "Science & Mathematics"
