To me it's about a girl whose boyfriend left her for a younger woman. After some time the original girlfriend started spreading rumors that the boyfriend had been missing her/had an affair with her. Eventually the boy's current girlfriend starts to believe the rumor and breaks up with him leaving him lonely. The original girlfriend feels bad for telling lies, but is glad that she got back at his cheating ass ;)
