I really like this song. I thought it was about her going out with a guy but he always had another girl who had him wrapped around her finger and she's angry cause she was the one that was always there for him. This new flame just came out of no where and it's like she has this power over him. And she's just saying that this new flame of his will only leave him in the dust and she's over the whole thing. She's ready to move on after venting =)
