Congratulations on the upcoming wedding!!! I think that in the day to day of it things won't be a whole lot different, especially since ya'll have been living together for 3 yrs. My husband and I had lived together for about a year and a half before we got married, we just celebrated our 5th yr anniv., and yeah we have our ups and downs, but that is what marriage is all about. You get through those times Together and you become closer and stronger because of it. We don't always agree, but at the end of the day I know that he is ultimately there for me, is my lifelong partner, and my very best friend. And that's what I look forward to everyday.
