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 to come back you say you'll be true
I know that I should I wish I could say no to you
Say no to you tell you it's over
Don't unpack your bags I 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 truth and I don't know what to do
I know I should I wish I could say no to you
