She married her first cousin who loved her all his life. However, when he was affected by porphyria she pretended that she feared him, even though he would never hit her nor any officer, though anyone else was fair game. She also disliked the simple life he had forced upon her, for as a Queen she expected a court, and moreover, a Court which held many balls. 
She liked to gossip, was a bore and a snob and, as the daughter of an English king, looked down on the Hohenzollerns. She turned her children against their father and created in her own apartments a far more civilized environment which her children loved. She indulged in politics and her main aim was for the "English marriages", 
specifically that her children, Wilhelmine and Friedrich, would be married to the Prince of Wales and Princess Amelia. However, neither took place as her husband opposed them for the simple reason that the two fathers loathed each other. Lord Hervey described the feelings of George II for his sister as "he had the contempt for her she deserved and a hatred she did not deserve". 
One positive thing about her was her attempts to have her mother, the Prisoner of Ahlden, released; and in this she almost succeeded. However, she was no support to either her husband or children. After her husband's death, she retired to the small palace of Montbijou in Berlin. Even though her son, the new king, visited her almost daily, she had no political influence.
