Dear [recipient's name]:

I still need to pinch myself, to get myself to realize that I'm not living a dream or fairytale-that this romance we're sharing is truly real. I never imagined that falling in love for the first time could be so exciting, fun, and fulfilling. You are everything I ever wanted-and more. Thank you for being who you are, and for being in my life. I savor every moment we have together and just cannot wait to make more memories together. Happy Valentine's Day!

With much love,

[Signature]
