Evdokia was very traditional, yes, married to a traditional Czar she would have been perfect, but married to Peter the Great-no. As for Peter II, he was very young, and it's hard to judge, before I read this thread I hadn't realized he was so...wild although he was but 14. I had heard that it is possible that Elizabeth Petrovna and him were lovers, and it's possible, knowing the both of them. As for Evdokia, she was rather traditional, so one wonders about any adultery charges. Henry VIII used that to get rid of wives as well.
