After her visit to the servant Christophine, Antoinette tells her husband the sad story of her family, as Christophine advised her. Though Rochester relents a little, she gives him Christophine’s love potion, which makes him sick. Thinking he has been poisoned he sleeps with the servant Amélie for a revenge.
Antoinette, who has heard it all, runs away and when she comes back she gets drink.
Far from her former happiness, Antoinette is now revolted.
A - The family
She brings both her father and her mother into the scene to put Rochester to shame.
She reminds him that her mother was a victim of injustice by the English government (no compensation money), by the white community (she was a kind of outcast pariah); she is a victim of fate too (destiny): her only son was crippled and died early, her property was burnt down.
Finally, she was abused and probably raped by a black couple before dying an insane woman.
She idealizes her father into a heroic knight who would have come to save her.
B - Slavery
Antoinette alludes to the way planters used to treat their female shaves accuses Rochester of doing worse with Amélie (l.13-15) taking advantage of her then quickly getting rid of her.
C - Rochester’s unfaithfulness
Antoinette hints at Rochester’s sleeping with Amélie (l.13). But she doesn’t directly accuse him.
Maybe she doesn’t really care about his sleeping with Amélie.
What she cares about is his not loving her, is the fact that she didn’t love her.
She seems ready to forgive him. “Don’t you love me at all?” (l.38).
She might put up with unfaithfulness if she had his protection. “It’s not the girl” (l.32).
She can’t bear his destroying the cocoon in which she sound safety (l.32-35).
Now she has fallen what consumes her, not Rochester’s brief affair.
There seems to be no recovery now from such antagonism between Antoinette et Rochester (things are past recovery).
