I disagree with all three of the comments above. I think they all have pieces, but allow me to put it together. This is a song about a guy who had grown attached to a girl who was spreading lies about him to his friends. His dad told him that no woman is worth that kind of trouble, and that he should walk away from the relationship. He does, knowing he'll get along somehow, and she'll be stung by her own poisonous lies in the end. It's pretty obvious, this is one of the most plainly written songs around.
