Maybe it's because a friend of mine has just got out of this type of relationship but what I read and hear in between the lines is a story of a "playa". A guy who flirts and gets in a relationship with you and later you find he was doing the same with other girls too. This song is how you break up with him. You found together the "sacred ground" that is the foundation of a strong relationship but his actions burn it down. Now tell him to "cut the love song", it's over. He "must be replaced".
