Apparently he was a basically good man, but his "impetuousness" as a young husband did not make for a happy bride. Marie was too young, inexperienced and overly romantic for such a practical and not-terribly-subtle young man. Their relationship seems to have been defined by these unfortunate first days of their marriage.
Quite frankly, though, I wonder if Marie would have been happy with George or indeed any other man for a prolonged period of time. She wasn't quite as fanciful as Carmen Sylva, but all the same Marie was highly dramatic and exceptionally ego-driven. I find her fascinating, but I don't think she was cut out to be a domestic, self-effacing sort, and if she had married her tempermental cousin George I wonder how her flightiness would gone over long-term, especially in a country that prized dutiful consorts! Seemingly impassive Nando and frivolous Romanian society seem to have been her better match.
