Falling for the Heart-breaker

The moment I met him I knew he was trouble. Constantly in my way, everywhere. It's like he knew my entire life. But I didn't know him. I didn't know a thing about him. He was always there. Wether it was watching from the sidelines, to nearly meters away from where I stood. Always there. Always watching. But who is he? He has yet to tell me, and it seems as though he won't. But if he does, I'm just hoping he doesn't end up to be just another heart breaker. And if he is, you can bet to hell I won't be falling for the heart breaker.
