Marriage is one of the most important events of people's lives and when it happens, it could have both positive and negative consequences. There are different types of marriage such as traditional and modern ones. In traditional marriage, there are some marriage arrangements where man and woman can meet and talk for a short time and in case both parties are interested, marriage is initiated. There is also another type of marriage where girl and boy meet each other for a while, in some events, they may have some limited or unlimited relationships, and once they are interested in each other, they may marry each other. This relatively new type of marriage is popular in many western countries but it is still a controversial type of marriage in eastern countries. In this paper, we perform an empirical study on the effect of pre-marriage relationship on long-term marital status. The results indicate that pre-marriage relationship can reduce after marriage conflicts. The people who had pre-marriage had less aggressive behavior compared with the people who did not.
