I think that is a pretty good sumning up of Michael's love life. He was happy with his morgantic wife, and although she was unsuitabe by the standards of Romanov marriage, she was more than a fling. His relationship, or the lack thereof with Patsy, was completely baseless. It's kind of too bad that it was though. As for Beatrice, she would have made him a great wife, but it was a relationship also unsuitable by Romanov marriage laws, she being very Royal, but a first cousin.
