My husband and I were together for 6 years, we got engaged, bought a house and lived together for almost 3 years before getting married. (we got married Oct 13, 2001) And I learned more about him in the three years we lived together than I did the 6 years before that when we both still lived at home with our parents.

So my answer is Yes, I think you should live together before you get married because you never REALLY know a person until you live with them!!
