Why

You use to be my best friend
You use to be my everything
Then you just turned on me
Why couldn't you just let me be happy
I don't know what i did
I don't know why i deserved this
What made me take you back
How Stupid can i be
After what you did to me!! This is just so wrong
Now i know who my ral friends are
But i still don't know why i let you back in my life?
