Why does it matter?

You said you loved me,
........You made me cry.
You said you’d never leave me,
........You walked out and never came back.
You said you’d fight for me,
........You gave up on us.

Whatever happened to you?
........I don’t know.
What happened to our love?
........I don’t want to know.
What happened to me?
........I’m afraid that was you.

Why am I in pain?
........You caused it.
Why do I still cry?
........Because I still love you.
Why does it matter?
........‘Cause you are the world.
