Leave my real boyfriend for my virtual lover?

Dear Friend,
Sex doesn't suddenly re-ignite love unless that 'love' was lacking in much-needed depth. What exactly does he mean by "the way you are"? What sort of change does he desire? To be honest, I doubt this relationship will be okay. After six years, he tells you he has fallen out of love with you? Do you know how long he has really been feeling that way? What is keeping him with you then and why is sex the only thing that supposedly rekindles his love for you? How drastically is he asking you to change?
