Lyrics:

When he was seeing her
You could see he had his doubts
And now he's missing her
Because he knows he's missing out

Now it's haunting him
The memories like a ghost
He's so terrified
'Cause no one else even comes close

He's a 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 - undeserving mess
Who would believe my life
Would be so blessed - life would be so blessed

Two years ago
He left all that debris - left all that debris
Who would of known
He would leave everything I need

He's a 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
If it wasn't for him
He would 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 that I would hate to be
I got the girl and he's left with just the memory.

He's a 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
If it wasn't for him
He would be as happy as me
