2.Paul Eaton,56,and Dawn Pitman,48,first met when he stayed at her mother's bed and breakfast hotel in 1982.The couple enjoyed an 18-month romance before going their separate ways because Ms. Pitman,then 21,thought she was too young to settle down.
3.They both met other partners and had children in the following years,but never forgot about each other,then in 2008,water board worker Mr. Eaton joined social networking website Facebook, where he saw some pictures of Ms.Pitman on holiday and got in touch.The mother-of-one,a care worker from Exmouth,Devon,said,"I went to America on holiday and my niece Rachel put all these pictures on Facebook.The irony was that I told her to put them off because I felt it was an invasion of privacy and she said she would get them around to it when she had time.If I hadn't been on Facebook,he would not have contacted me and we would have never got back together."
4.Ms.Pitman later mentioned,"I did think of him quite a lot over the years and wondered what happened to him. He hasn't changed a bit.He's the same old laid back,easygoing Paul I knew all those years ago."Mr. Eaton,a father-of-two from Bransley,South Yorkshire said:"It was totally a chance thing. I had only been on Facebook for one day.I just typed Dawn's name in and I hoped for the best.It was a bit scary when I contacted her. I thought she might be married and would have a dozen kids."
5.The couple met up again on New Year's Eve 2008 and were amazed to discover the intervening years had been kind to each other."It was a real shock,"Mrs.Pitman said,"We both saw each other and he was exactly the same as I remember and that's what he said about me.He hadn't changed a bit.I knew then he was the one for me."
6.Mr. Eaton added:"We just knew instantly as soon as we met up again.We didn't even have to discuss it or propose.When we knew each other all those years ago,I was a white van man and Dawn had a sports car. I still got a white van and Dawn still has a sports car. Some things never change.She always said that we would see each other again.I just didn't think it would be 27 years."The couple are due to get married in Exmouth on March 20.
