I know  I should I wish I could say no to you...

I should have known from the start you would cause me the grief
Cause it tears me apart each time that you leave
Now you want [bad word] back you say you'll be [bad word] 
And I know that I should I wish I could say no to you

Say no to you tell you it's over
Please [bad word] back I just don't love you anymore
Nights when you would slip away I pretend not to see
I have hoped that someday you would stop hurting me
Now I'm faced with the [bad word] and I don't know what to do
I know I should I wish I could say no to you
