Some reasons of divorce

Although I am too young to have a marriage and to experience the real marriage life, I still want to know why there is always someone who gets a divorce and loves to be single so much.
To begin with, as the saying goes in Chinese, “marriage is the grave of passion”. People enjoy both love and freedom.Some people prefer the former, thus they have a family,peace and happiness. Others may can't stand being bound by marriage. But stimulation isn't fit for the marriage .Problems are growing.And one day when the quarrel bursts out, they will break up.
In my opinion,the second biggest hinder in marriage is disloyalty. Love is a power between the lovers. Like a conversation, no one can continue if another leaves or stops . When one can't resist the temptation ,it's a signal that the marriage is near the end.
