Passage: Though queen, as an unmarried young woman Victoria was required by social convention to live with her mother, despite their differences over the Kensington System and her mother's continued reliance on Conroy. Her mother was consigned to a remote apartment in Buckingham Palace, and Victoria often refused to see her. When Victoria complained to Melbourne that her mother's close proximity promised "torment for many years", Melbourne sympathised but said it could be avoided by marriage, which Victoria called a "schocking [sic] alternative". She showed interest in Albert's education for the future role he would have to play as her husband, but she resisted attempts to rush her into wedlock.
What was the marital status of Victoria when she became the princess?
