"Must be nice"
Oh god.
She regrets it, for the first time she regrets it. I can see it, I can feel it and its killing me. Please Rose, don't regret it. I couldn't stand it if you did. I love you so much it hurts me, and theres nothing I can do, your not mine, and you wont ever be, but I do love you so much it hurts me.
Please, any other emotion, but not regret.
