Why do you think most people get divorced? Is it lack of independence or sexual incompatability or something else?
I think it is that people just don't match each other anymore. I think they may fall out of love or drift apart. 
I think sexual incompatability is the biggest reason personally, it leads to a lot of divorce directly or indirectly
Some probably have to do with that. I think a lot of people get restless and have a "grass is greener on the other side mentality." There is also a lack of commitment from a lot of people. 
i think most of the countries with arranged marriages have low divorce rates, why do you think that is?
