Happy anniversary! I'm writing this letter to remind you that I love you. I know that things have been a bit hard for us lately, and we have both hurt each other, but I really do believe that it will be okay now.
I love you more than I can say. You are the most important thing in the world to me, and I would do anything for you. You make my life complete and I am only happy when we are together.
I know that we can't be near each other at the moment, but if we just put up with being apart for a bit longer, it will all work out, and it'll be worth it in the end. I want to spend the rest of my life with you. I want us to grow old together. I hope this is only the beginning.
