I can't go on like this forever..

I know that you love me, and I love you too. But there is something deep inside, eating me alive. It's this feeling I can't explain. I know you'd hate me for this but, I'm in love with someone else. I don't know how I could ever tell you this, because I know we're perfect for eachother. But this other boy, he is so sweet, when he wants to be. And his eyes.. I could gaze into them forever. So, I'm sorry I really am. But I don't know how long I can go on, I feel like I'm living a lie, and I just can't go on like this forever..
