In today's society, there is an increase in the percentage of couples that live together without getting married. They think getting married is just like a piece of paper, which they can tear it apart any day. They believe that living together without marriage allows for more freedom of happiness, which make their relationship are more stronger and more powerful than getting married. They believe marriage confound them to severe restrictions. If couples get married, they would have to take care of their children and support their families financially. If marriage did not exist in this world, divorce courts would not exist either. I strongly agree that living together without marriage is a good idea because people can have more freedom to do whatever they want to do, such as can go home late, just have a little responsibility when their partner get pregnant, and don't have to support each other financially.
Nowadays, many couples cannot live together permanently. So they like the way of living together without getting married because if one of them likes to break up, it's going to be more easily than married couples. My uncle Hung is 40 years old, who doesn't like an annoying when he comes home. His partner (a woman who lived with him for 3 years ago, but they didn't get married) didn't care or yelled at him when he came home late. He told me that was a good point of living together without getting married because he had never explain where did he go or what did he do. Also, I think it's a good way than married couples because when one of the married couples come home late, they have to explain to their wife/ husband.
Pregnancy might have on some couples that live together without getting married. They might not have any responsibility to each other, but they have to figure out how to solve the problem for them selves. Also, it's a little problem for them to decide who is going to support the child when that child is coming to the world.
