Among the European nobility, divorce was social death, but dalliance was definitely not. While Marthe and George continued in what was sometimes actually a mutually supportive partnership, they pursued their own interests. The French prince Charles-Louis de Beauvau-Craon fell in love with Marthe, an affair that lasted for a decade. In Paris, she also encountered the Roman Catholic Abbé Mugnier, who converted her from her Eastern Orthodox faith, and she began an extensive, frank correspondence with him that was to last 36 years.
