When he was seeing her      You could see he had his doubts   And now he’s missing her      Because he knows he missing out   And now it’s haunting him      Her memory’s like a ghost   And he’s so terrified      Cause no one else even comes close      He’s the guy that you should feel sorry for   He had the world, but he thought that he wanted more   I owe it all to the mistake he made back then   I owe it all to my girl’s ex-boyfriend      So then along comes me      This undeserving mess   Who would believe      My life would be so blessed   Two years ago      When he left all that debris   Who would have known      He would leave everything I need      He’s the guy that you should feel sorry for   He had the world, but he thought that he wanted more   I owe it all to the mistake he made back then   I owe it all to my girl’s ex-boyfriend      If it wasn't for him, I would still be searching   If it wasn't for him, I wouldn't know my best friend   If it wasn't for him, he would be able to see   That if it wasn't for him, he'd be as happy as me      When she and I settle down you can bet   That he is going to have to settle for less   He's someone I would hate to be   I got the girl, and he’s left with just the memory      He’s the guy that you should feel sorry for   He had the world, but he thought that he wanted more   I owe it all to the mistake he made back then   I owe it all to my girl’s ex-boyfriend      If it wasn't for him, I would still be searching   If it wasn't for him, I wouldn't know my best friend   If it wasn't for him, he would be able to see   That if it wasn't for him, he'd be as happy as me
