Simple. It's about this girl who has become so psychologically damaged from an abusive relationship that she ends up committing suicide by shooting herself with her boyfriend's gun. In a way, the song talks about domestic violence and how it can impact the life of someone, to the point where they become suicidal because they don't want to live that life anymore. This song doesn't encourage domestic violence, but talks about why domestic violence is bad by telling a story about how an abusive relationship ended up in the girlfriend committing suicide.
