Questions

As yet another member of my inner circle's marriage is in trouble, it got me thinking about divorce. How come those who got married by choice (= love) have a higher rate of divorced than those who had arranged marriage?

OK, We can assume that those who agreed on arranged marriage are more conservative, so they tend to avoid divorce. However, in the USA, according to Barna Research Group the rate of divorce in the conservative Christian group is significantly higher than in the Atheist/Agnostic group. So what give?

I also know that those who live together prior to getting married have a higher rate of divorce. Is it because that piece of paper makes one take one's partner for granted?

Or is it because of the high expectation and bigger ego in one or both of partners that lead to high divorce rate? Why cant we compromise?
