He knew they could never be together. Not even if fate was on his side, he could and would no longer be with her. They might still love each other, they might still have feelings for each other, but they both know, they can't be with each other. It's as if a rope was pulling them away, letting them know that nothing could let them be together. He knew he hated himself, for being a coward, but as he sees that new guy she was with, he couldn't help but say, he's a lucky guy.
