I have a bit more time for Elizabeth than other folk have. She is clearly someone who finds it hard to empathise with others, or even see things from other people's persepctives, but I think it is important to remember that she was still young (15/16) when her mother died and she was suddenly thrown into this extremely unhealthy relationship with her father. She effectively became his consort. Without getting too far into Austenuations territory, Emma had a similar experience, but has the counterweight of Miss Taylor and Mr Knightley, and her father is a different man. Elizabeth clearly does not have the same relationship with Lady R as Emma does with Miss Taylor.
