Why

I knew that you could never care about me, so why did I even try?
I knew you would never shed a tear over me so why did I cry?
I knew you could never love me, so why did I say that I loved you?
I knew I never would be the girl who had won your heart, so why did I try to break through?
I knew I would never be able to hold your hand, so why did I grab for it that one day?
I knew that everything you said were lies, so why did I believe what you had to say?
I knew that you were a bad boy, so why did I say you were good?
I knew that you never made sense, so why did I say that I understood?
Well I guess that I thought it was all worth a try,
Now the only question I have to ask is why?
