I think this song is about a girl that he (the narrator) has had a long relationship with, then he sinced it was ending (or started to have feelings for another girl.. or was cheating on her) so he broke up with her. Then she was so sad she killed herself. The chorus is kind of the narrator rationalizing his actions or looking at it from her side of the story.
