Why?

Why did you lie to me, why did you make me sad...
why did you ignore me when you knew it made me mad...
why weren't you there for me when i was having a bad day...
why is it that we have nothing left to say...
why did you act differently around your friends then when we were alone...
why did you tell me to call you back when you knew you weren't gonna answer your phone...
why did i let myself sit by the phone, when i knew deep down you weren't gonna call...
and why did you tell me you love me when it seemed you didn't care for me at all..?
