Drive Myself Crazy

I'm making this so crazy. I am just don't know what to do. How can you tell someone that you can't love them anymore? Even if you know that you will always love them. It the hardest thing to do, to turn around and walk away pretend I don't love him. So what should I do. His confessions and his heart exploding to me as if he thinks he can change everything. Why must this be so confussing.
