I Should Have Known Better

And I should have known better 
to lie with one as beautiful as you. 
Yeah I should have known better 
to take a chance on ever losing you, 
But I thought you'd understand. 
Can you forgive me? 

I - saw you walking by the other day 
I know that you saw me, you turned away and I was
lost. 
You see - I've never loved no-one as much as you, 
I've fooled around but tell me now just who is hurting
who?
