Her presence haunts him even though she is gone.
He is living in a fantasy world,
he cannot escape the world in which he is now caught.
He has to find something to give him a reason to live again.
He has to learn to survive through the loss.
Pride tore them both apart and now he has nothing.
He is a completely different person.
He cannot look back on what has happened
he has to keep moving forward so that he does not get stuck in this world.
The world he is currently in, he will not be able to survive in.
She was his best friend and now she is gone.
He has to strive on alone.
