 Cheating in the past is important to this story, but that’s not what it  is about. Its about someone who is deeply conflicted about confessing  their love to their BFF’s ex. It’s about things I’ve experienced in my  life, from a number of angles. It's about pain and failure and being  human and hoping that maybe, just maybe, they love you too.  Also, if you think that someone can’t be as oblivious as this dude must  have been, let me assure you from the depths of personal experience that  you can.
