Rosamond Vincy — Vain, beautiful, and shallow, Rosamond has a high opinion of her own charms and a low opinion of Middlemarch society. She marries Tertius Lydgate because she believes that he will raise her social standing and keep her comfortable and carefree. When her husband encounters financial difficulties, she thwarts his efforts to economise, seeing such sacrifices as beneath her and insulting to her on the part of her husband. She is unable to bear the idea of losing status in Middlemarch society.
"Middlemarch" by George Eliot
