I wonder where the attraction was for her - she had children the same age, was married for many years, had responsibility for her own family, her job (not sure how this worked out in France, here in Germany you would loose your job and not get it back anywhere else). As I said: If he had been 20 or something, it would have been different.
Oh, I don't know, Germany is rather lenient in that respect. A teacher at the Fairies' school fathered a child with one of his underage students and since they are now happily cough married, nothing happened.
