You...

Seeing you with her killed me

But I guess it wasn't meant to be....

I hate her but you hate me

You had my heart but threw away the key.

 

You were my world

Everything and more

But you destroyed it all

And shut the door.

 

Now I'm all by myself

Not worried about health

And I barely eat because of you

But you just say I'm weak

But I thought you didn't care?

Oh wait, that's only when she's there...
