I don't think aviation is that much differnt from any other major profession. How much sacrifice (of personal life style) do you think doctors had to make to get through all the years of schooling and internship? How about architects? Lawyers? And I can tell you from personal experience --- even the fat cat investment bankers in the city work 80 hour weeks. It takes a "special" partner to hang in there through the long years of little reward. If she left now --- she did you a favour. Now get back to your flight manuals and back to work with 'ya mate.
