If one person decides to split themself down the middle... to become two, break away from the restrictions of being the person they want to be, and just like unbound, just for a while... and then, after living that way for a while, discard the second and just be the person they have always wanted to be... I see nothing wrong with that. Put away being yourself just for a while, all those things you said were too messed up to do, all those things you couldn't do...
Divide yourself, put the original away and walk as a different person... talk as a different person, act as a different person... and when it's all over, discard that person and go back to being you. Blame it on him... but then, it never happened, right?
....Right....
