I am thinking while it is quite possible that there is some of that --smoldering resentment and jealousy-- in Elizabeth's attitude towards Anne, I am inclined to think that the greater portion of her treatment of Anne is in Elizabeth's character - so like her father's. Along with some of the more eloquent descriptions of Elizabeth in the posts below, I would say that Elizabeth is superior and self-centered, and hardly has time to notice Anne, for Anne has nothing that Sir Walter or Elizabeth consider of value. I cannot imagine that Elizabeth would have been jealous that Anne had received two proposals, because she would not have valued either of Anne's two suitors, so far beneath Elizabeth as she would have considered them both.
