She was my once in a lifetime

Happy ending come true

Oh I guess I should have told her

I thought she knew



She said I took her for granted

That's the last thing I would do

Whoa I'll never understand it

I thought she knew

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 have known

I should have known



A heart full of words left unspoken

Now that we're through

I'd sell my soul to have this silence broken

Oh I thought she knew

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 have known

I should have known



She was my once in a lifetime

Happy ending come true

Whoa I guess I should have told her

But I thought she knew

I thought she knew

I thought she knew

I thought she knew

I thought she knew

I thought she knew



Oooooooo

Oh I thought that she knew

Yeah ooooooo
