Can't. Stop. Plotting.

What if the girlfriend doubts his stories all along and rather than the parallel stories being reality they are her imagined alternative to his fantastic stories? She imagines what his real life is, because other than his word, which based on all of the other lies he has told her is near worthless, there has been no confirmation or proof that he is anything that he says he is. So following his tales is her imagined alternative, one that is much easier for her to believe. She clings to the reality that she has created for him, and he begins to suspect that he is not believed.

Whose tale is closer to the truth? What will happen will happen when the man’s past is proven one way or another? Will the girl be abandoned for her mistrust, rewarded for standing by her man or will she stay will a complete liar?

Do I leave the reality of the man’s past a secret to the reader? Do I leave to the end the truth about his identity? Is this a fairy tale or a cautionary tale?
