Bitterness Burnt lyrics

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.
