He is over 70, married for 38 years with grown up children. She is 54, a single parent and devastatingly attractive (obviously not me). He has some of the problems that come with old age and poor health but is a reasonably attractive man. She has never been married, has not been able to maintain a relationship and her chidren's father left her when they were small. They are having an affair in the town where both of them live and say they love each other. She doesn't want to live with him and he is telling her he will tell his wife and arrange to live alone. They have been creeping about with this relationship for 3 years, he lies to his wife about going away rambling at weekends and goes off with her. What will happen to them?
