I am stating maybe it was a family trend. Anyway according to the letters she wrote home from Greece, Elisabetta was trying to fit in with the Greeks but she was never given the chance. Poor George was torn between his love for his wife and loyalty to his mother. When the marriage turn out childless, Elisabetta became bitter as she so hope to give George a child. All these information came from her letters to her mother Missy. Elisabetta might be a nasty bitter woman, but she sure wasn't born that way. After living in relative proverty with the Greeks, she suddenly became a rich woman after her father's death. That's when she start to throw her weight around as her marriage began to fail. The death knell was the divorce of Karol & Helen. George supported his sister, while Elisabetta supported her brother. Headstrong and passionate, Elisabetta's life became turbulent right up to her death.
