The reality of having someone have to tell you over and over again that they will never be able to be the person you want them to be is a hard pill to swallow especially when you think that you're being reasonable in your expectations. Eventually it does sink in though after a lot of tears and sadness. Eventually you realize you can't continue to beat your head against the wall, you just have to move on and accept defeat.
I'll always love you and want the best for you, even if you don't want it for yourself. You are such a beautiful, intelligent, awesome person that it kills me to think you're not ever going to be mine again. I hope we can stay in each other's lives. You're my best friend and I will always love you.
