This probably isn't something that I'll send her but I just needed to write it out somewhere:

Baby you're so beautiful. I know you feel like you can conquer the world today, and that's because you can.

It probably feels like you'll have all the time in the world to find someone else.

But I want you to know something. In a couple of years, I'm going to be the greatest catch a lot of women can only dream of.

I know I'm not worth as much as you are today. But things will change baby. Your beauty will fade and my status will grow.

You don't understand that I'm giving you the chance of a lifetime. It's so tragically true, youth is wasted on the young.

One day you'll learn, you let someone amazing go. And no matter how much I love you and cry for you today, that person I become tomorrow won't have any sympathy for a woman who left him when he was still growing into the man he would become.
