Noble's book examines our reactions when a first love makes a surprise reappearance later in our life.  Yesterday Elizabeth Noble said: "It's much easier than it used to be to track down people from your past, using Facebook and other forms of social media.  "But that doesn't mean it's always a good idea.  "If you're lucky, you will have fond memories of first loves, but even if you've aged, I'd argue you learn to take things forward into future relationships that can make those work better and stay stronger."  The study found a large percentage of men claim to have loved someone who didn't love them back.  Men were also more likely to say 'I love you' first and were also more likely than women to pine after their first love.  Both sexes agreed their first love was the one they took the longest to get over and one in four said they didn't think they would ever fully recover from the heartbreak their first love caused them.  Men were also more likely to regret splitting up with their first girlfriend.  Women were more likely to be happy with the decisions they have made and more realistic about how happy they were in the first place.  Although women were more likely to try and track their ex-partner down over the internet and keep track on him and who he is dating.  Overall one quarter of Brits think about their first love at least once a week and those that are still searching for the right partner are more likely to reminisce than anyone else.  One quarter of Brits still think they haven't been in love.  Men in the north fall in love quicker than men down south, with Londoners cynically taking the longest.
It might have come as a surprise to Casanova but men fall in love more easily   and more often than women, research suggests.
