This might be a continuation of the narrative from the song Sim Sala Bim which plays just prior to this one on their album Helpless Blues.
But, even if it doesn't I feel the message here is that a man realizes he's forsaken the love a girl gave him. He now realizes how much he wants that love but has to live with the fact that she is moving on. He feels as if the new man, is bad for her and that she is embarking on a terrible journey because she is naive having never known what love is.
