Why does Elizabeth feel she will never see Mr Darcy again when she told him about Lydia's elopement with Wickham in Pride and Prejudice?
If Lydia marries Wickham, then Elizabeth will be closely related
to a man Darcy detests. If Lydia fails to marry Wickham, then
Elizabeth will be a member of a disgraced family. Either way a
connection between Darcy and Elizabeth is also a connection between
Darcy and a scandal.
Lizzy is already aware of the enormous differences between her
situation and Darcy's. She is poor and he is rich. In England of
the time, that was regarded as a reason for them not to be married,
because marriage was a way to form alliances and increase wealth.
Darcy has commented on this. Her family is not well bred by Darcy's
standards, and Darcy has commented on this also. She has already
turned down a marriage proposal by Darcy, and rather angrily. She
regards the attraction Darcy has for her as probaby very weak to
begin with. Lydia's elopement, in her view, is just a final
straw.
