The situation started with IF "The GF open the door and see her BF with another woman, the song explain how they on the bed togather and had sex" so she hesitate what she's gonna do 1.kill em all 2.just close the door and leave 3.walk into kitchen take the knife to kill that woman or kill her BF the wait until police take her castody. but still has its own detail a lot more than i just explain.
The song explain what's going on in the girls head. All the ideas were not executed, in the end the girl could only stand still and cry... being sad for what had happened.
