Before I tell you the factors that lead unhappy marriage

Before I tell you the factors that lead unhappy marriage, let me show you the trend of divorce rate. In this table, you can see that the number of divorce decrees is getting higher and higher. In 2006, there are about 17 thousands of couples getting divorce. But why do they have unhappy marriage even end in divorce?

Firstly, some couples may get married because of premarital pregnancy. In this situation, we can see that the partners have fatuous love. Although the partners have passion to share sex and have a commitment to take care of their baby, they may have not yet develop other aspects of true intimacy and may lack a real understanding of who they are marrying. It has many problems that leading they have an unhappy marriage.

Here is an example of it. Ada and Ken get married because of premarital pregnancy. But they need to face lots of problems such as mentally and financial problems. And Ada have bad relationship with Ken’s mother but Ken doesn’t help Ada to solve the problem. Finally, Ada regrets to get marry and have the baby.

Next is poor communication, mother Teresa said “if youjudge people, you have no time to love them. Couples may have do so that lead unhappiness. The reasons are couples may busy in work, so they do not pay attention to or concern with their spouse or even have conflicts with their spouse such as household task. They will complain their spouse, for instance, "He never listens to me when I talk!"
"She talks and talks, but never actually says anything!"

Another factor is the partners get married too fast. They have infatuated love because they only have passion to get married. They do not have deeply understanding to each other.
