Pretty sure it's about his dad. He wrote some pretty strong and not-so-good stuff about his dad in previous songs: "I turned a bit of my pain into a song". But now he's forgiven his father, but can accept it if his father is hurt for his previous comments "You took my shame but maybe that was wrong" Hopefully I'm making sense.
The father theory also fits the line: "Because the blood in me is your blood every time I fall"
