Here is one I wrote for my fiance of 4 years :
To My One & Only, On Our 4th Anniversary Together
I love you so much. That you already knew. It a continuos love that has grew and grew.
We have been through so much, the good and the bad but this is the best time in my life, I have ever had.
You make me laugh everyday of my life and I know we were meant for each other beuse it feels so right!
I am so greatful to have you by my side everyday. You make me feel so loved and cared for in every single way.
Now four years have pasted us and it seems like it went way too fast. Every day I find myself looking back at our past.
Four years ago today, we were up in your room just talking like we were old friends and stayed up with the moon.
Then that very first kiss when you took my chin for our eyes to meet and kissed me and right there I knew you I would keep!
The rest of our lives started then and we didn't even see. Look at how far we came with just one kiss, you & me!
Forever, I love you my one & only, my honey , my love.
