Would it be a factual autobiography style book, or fiction? I could see a good fiction book being made out of the plot of a man who has an imaginary wife his whole adult life, but who eventually meets a real woman, and has to deal with the conflicting emotions he has between this real person and the imaginary being he's loved for so long. Writing it as an autobiography would also be very interesting because the concept is so unique. It would make an excellent addition to the "autistic autobiographies" already on the shelves. I would probably read it.
