You aren't really new, but it's taken me awhile to get to know you. I'm glad I finally did. You are my best friend, and the person I most like to spend time with. You have always been there for me, and :::insert other cliches here:::.
I don't get to see you very often, and it's a little too embarrassing to date you in public, but you know that I would if I could, right?
Our relationship is so hard to explain, and I know it's a little damaging to both of us, but I don't want to end it. You're amazing and wonderful and I love you. You make me smile, and I love the nights we have together. When the winter comes, I suppose you'll be leaving me, or I'll drown my sorrow in hot chocolate, because winter isn't really our time, is it? I'll treasure the summer, though, baby, and I promise to always write corny and sentimental things about you in my journal forevermore.
Love,
Me
