Although some people don’t allow couples to live together before they get married, I really believe that domestic partnership can be good for each other. First of all, you have time to know him or her. Most people live different environment, so you can hardly to all understand your lover. To live together makes understanding to each other (his or her thinking, behavior and even small things). Second, when you live together before get married, you can save money. As everyone knows, Rent for houses is  high. It is clear that one house is more inexpensive than two house. After you save enough money, you won’t late to get married. Most important, you can make a choice that you get married or not to your lover. You must think carefully before you get married. Marriage is your whole time, so you have to consider about him or her who is really a soul-mate of you. If he or she is not your perfect one, you are willing to give up. In conclusion, although some people insist couples should not live together before they get married, I believe that is necessity.
