Living blithely ever after is not all it's cracked up to be. One person in five of us living with a partner is in fact craving for someone else, according to a survey. That means just under five million either living with a partner or married could have sexually longings for a third one. And the woman or man of their dreams is probably to be a colleague or among their circle of close friends. Even those who were completely content with their other half did not escape unscathed. Just over 50 per cent of these admitted to sometimes having feelings for someone else. One in six of those who do fall for another will follow their hearts and embark on an affair. 'The research shows just how many people believe that it's possible to hold feelings for more than one person, ' said a spokesman for the polling firm that carried out the survey. 'Even in a happy relationship, it seems to be possible to have a wandering eye or even crave affection from another person. As well as colleagues and friends, ex-boyfriends or girlfriends feature highly on the list of potentially dangerous love interests. Men are far more likely to fall for someone else, with 22 per cent declaring they loved two women. A spokesman from www.OnePoll.com said: 'Men have a bad reputation when it comes to eyeing up other women and the research proves this is actually true. 'Men are much more likely to "window shop" whilst in a loving relationship as well as falling for another women. The book 'The Craving' is written proving above given statement. This is the story of four close friends, Manoj, Sanjna, Himesh and Madhu. They are living with his or her partner happily, but there is something more in their minds.
