Dear [recipient's name]:

My Valentine, my knight in shining armor-you are that and so, so much more. I feel so special to be your wife and to share my life with you. You are everything I always dreamed of, ever since I was a little girl-strong, handsome, sweet, tender, smart, and wise. Our relationship just gets better and better every day, and I love that. Happy Valentine's Day to my one and only. Thank you for your love not just on this day but every day throughout the year.

Love always,

 

[Signature]
