Lyrics:

Here is Track 10 of Bowling For Soup’s 7th album which was released in 2004.
When I came home my stuff was on the lawn
I thought she was happy, but I was wrong
The note she left, it took me by surprise
Said I've turned into some other guy

The things she says that she gave up for me
She says it was a waste of her time

Guess I don't really know what I was thinking
Would've thought we would float, but we kept sinking in
Things were so good, but you were in love with some other guy
He looked just like me, but I make you cry
You know I don't mean to, I'm just an asshole sometimes

I never saw myself as being alone
And maybe that was my problem, 'cause now she's gone
And I can't help but think of how things could be
And I hope she's happy, happy without me

And all the things she gave up for me
I took for granted time after time

Guess I don't really know what I was thinking
Would've thought we would float, but we kept sinking in
Things were so good. but you were in love with some other guy
He looked just like me, but I make you cry
You know I don't mean to, I'm just an asshole sometimes

And please don't think I'm complaining
I was just happy to have her for a time
And if you see her tell her I said
'Hello', and that I'm doing just fine

Guess I don't really know what I was thinking
Would've thought we would float, but we kept sinking in
Things were so good, but you were in love with some other guy
He looked just like me, but I make you cry
You know I don't mean to, no, you know I don't mean to
I'm just an asshole sometimes

Guess I don't really know
I'm just an asshole sometimes
Guess I don't really know
I'm just an asshole sometimes
I'm just an asshole sometimes
Guess I don't really know
Guess I'm an asshole sometimes
