Fiction Book

Hello readers,
I am in the process of writing a fiction novel about a guy who had his heart broken by the only woman that he loved for a very long time. The twist happens when he tried to create an image of a woman that would totally love him no matter what happens. He creates a very beautiful woman, understanding, loving and has all the traits every man would ever want right inside his imagination. The woman comes to life in his writings, social networks that he joined, e-mails and SMS messages. However, the woman is just a pigment of his imagination. He is actually the one sending himself e-mail messages.
Do you have any wise ideas on how I should go about with this one? Please send me some of your insights and I will try to compile them as I progress in the novel. I will recognize all the help I can get. Thank you and may you all have a wonderful day.
