... Because what I'm about to say is

... probably the most selfish thing I've ever said in my life

... I just have to say it once.You just need to hear it. 

... I love you,Elena.And it's because I love you that

... I can't be selfish with you

... Why you can't know this. I don't deserve you

... But my brother does.   God,I wish you didn't have to forget this. But you do.
