Bitterness burnt

Came in as no-one
Leaving as someone powerless
You were the sole one
Helpless you were alone

Left him for to grow
Untainted by his shadow
Blamed him not for it all
Just too well learned a man to fall

I want to get by
I want to return
I want you to fly
Only bitterness burnt

How do I get there?
How do I pass?
How could you leave
Without looking back?

Heard all you had to say
Though it changes not a thing today
Forgiveness is so much to ask
When findings re-write the past.
