Go ahead

I sit here and cry to you as my world falls to the floor
But you don't seem to care because you don't live here anymore
You dated this awful girl who then tried to take over my life
I told you it was wrong and that she was awful and you then made her your wife
You're no longer around when I need you
I would have left and been detached long ago if I knew
Knew that you would turn out to be a trader like all the rest
Yet you sat here with your family and pretended to give us your best
All the rest don't seem at all bothered by you leaving
But I'm the only one that you won't be deceiving
You're not as perfect as you'd like them all to believe
So go ahead pretend you're the best and go ahead and leave
