Happily married for 7 years.
We will be celebrating our 10th anniversary next April!
Wouldn't change much though, its great having someone that you know cares about you and will always be there for you no matter what. The biggest adjustment is that you can't do whatever you want whenever you want, there are some compromises that have to be made. Dang responisbilities, don't worry most of that comes after you have kids though.
