It is a myth that ones' race and or culture makes one a better spouse than another. People are compatible or not. It really is that simple. That said, I figure getting married is kind of like playing the lottery. I think I won the lottery.
Almost every gaijin I know, living in Japan, has been divorced. I am working on some general theories but have not really put them together. Would love to know what the divorce rate in Japan is between nationals and foreigners. I would also love to know the divorce rate of Japanese who marry outside of Japan to a foreigner.
It is hard for some to believe but I know just as many Japanese men who have married gaijin as Japanese women who married gaijin.
