I had to sing this song a couple of times to get what it really meant and I finally got it I had the same thing happen to me my boyfriend brady had another girlfriend for 3 weeks and I finally found out and he said after that we never dated because that first time I broke up with him he wanted payback so I think the song is about payback because it said you only think of your own pain week later he said sorry I forgave him but every time I hear this song ill think of him=(
