It is our 12th anniversary! You are the best thing that ever came into my life. I know we don't make big deals of our special days (guess that's the way it is with two introverts), but I wanted to tell the world (well, you don't have to worry about the world hearing, not many people really read this) that I think you are the best.
You are the greatest husband, and I am so proud to be married to you. There aren't words to explain how perfect of a fit we are together. I have so much respect and deep love for you. It seems to get better all the time. I love making future plans with you (even if it is only to decide which room to paint next!). We work together and live together so well.
This is not one of those milestone anniversaries, so I don't have to feel bad about not writing something a little more profound. Just know that you are so loved, and I am glad to share my life with the best guy ever for me!
