What is the success rate of marriage in your country?
In the states, about 3%.The success rate of people who have been married to get married is 100%. What else is there to succeed about? Rug-rats? Fences with nice hinges? I think there's a category mistake here somewhere. Marriages just are. And when they're over, they aren't anymore.
