Marriage and destiny

I have a question that confuses me often. I have read in the Islamic books that women is created from the left rib of the men and therefore matches are made before a person comes to this world. This means that each man and woman on earth has a match. Then what about the man who never gets married or women who never gets married when they have their match in the world. And if a person does not get married, what about his/her destined match? Does his match also does not get married? And those who pass away as a bachelor, does his women never gets married, as a person only gets married to those with whom they are destined to be with.
