I can't see Lizzy as determined to hate Darcy. I'd wonder why she bothered to turn away to hide a smile when Darcy claims that he has rid himself of charecteristics that may incur ridcule.
Lizzy also tries to check her mother's rude comment to Darcy.
My impression is she tries not to offend him.
] Personally, I think that Elizabeth did not have the experience to see that Darcy finds her attractive, but she should have seen he has grown more respectful once he has got to know her.
At this point, Darcy's attraction to her is aroused- yet held in check by his pride. Darcy is determined to protect himself from a woman he still regards as socially inferior to him.
Any potential admiration Lizzy could have for Darcy as a man of education is nullified by his uninviting manner.
If Lizzy shows prejudice, Darcy's behaviour had changed little since the Meryton Assembly. Regardless of his thoughts; his behaviour shows Lizzy he still regards her as unworthy of attention or even to look at.
At Netherfield, does Darcy attempt to discuss books with her instead of reading one ?
When Darcy spoke to her it was to cover the etiquette aspect; not to invite friendly converse.
If Lizzy were to consider anyone at Netherfield as a friend, it would be Bingley. At least he was friendly, trying to put Lizzy at ease and sharing her genuine concern about Jane who is Lizzy's priority at Netherfield.
