3. Future letter
Now this may not seem like a very important thing to do but this will surely make your marriage, even more, special. While dating, write a letter for your future spouse. Write about all the things you love about him or her. Write it for your partner in the future and how in the present you see each other being married together and living a happy life. Give this letter to your partner on your honeymoon or wedding day. Chances are, their love for you will quadruple.
