I think it's about that sometimes, you need some space and some time alone to find what life holds for you (fire needs a space to burn) . The speaker looks back at a relationship that ended. He thought he did it all right ( I thought I kept you safe and sound, I thought Imade you strong) then "something made me realise that I was wrong". He learnt that you have to find your own place in life, and then you burn brighter (I can finally see your light). Now that he looks back, the speaker realises what he has lost, but for the other person it was necessary that he let go.
