Do-do-do [Repeats]
She was my once in a lifetime,
Happy ending come true.
Oh, I guess I should have told her,
I thought she knew
Do-do-do,
She said I took her for granted,
That's the last thing I would do.
Whoa, I'll never understand it,
Cause I thought she knew.
I thought she knew:
My world revolved around her,
My love light burned for her alone.
But she couldn't see the flame,
Only myself to blame.
I should've known,
I should've known.
A heart full of words left unspoken
Now that we're through
I'd sell my soul "to have this silence broken"
I thought she knew my world revolved around her
My love light burned for her alone
But she couldn't see the flame
Only myself to blame
I should've known
I should've known
She was my once in a lifetime,
Happy ending come true.
Whoa,
I guess I should of told her,
But I thought she knew.
I thought she knew,
I thought she knew
I though that, she, knew,
Yeah
She was my once in a lifetime,
Happy ending come true.
