More things to question! Did Nelly benefit from Catherine's death? Did Edgar withdraw from the world because his reputation was tarnished?
With Catherine's death, Nelly became governess and the only woman in charge at Thrushcross Grange, answering only to Edgar and no one else. She reached the maximum power someone of her social standing could attain. Also, unconsciously, Nelly may have wished for Catherine's death because, from her perspective, Catherine's behavior ruined the Linton family.
Nelly said: "'She's either unconscious or dead,' I thought: 'either way better. Far better that she should be dead than lingering a burden and a misery-maker to all about her."
Nelly recounts it as if Edgar became reclusive because of the great pain of losing his wife, but what if it wasn't as she says and there were other social reasons for his seclusion?
Since Mr. Lockwood didn't speak to anyone else in those parts, he was left with only one version of what had happened, without knowing how the people there viewed it.
At that time, the betrayed man faced profound public humiliation. The severity of the damage depended on how he reacted. If he accepted it passively, he became a laughingstock. Edgar probably became a cuckold in people's mouths. The situation would become a social and psychological nightmare for a man with Edgar Linton's proud and reserved temperament. The betrayal exposed his inability to control his wife, seen as his natural subordinate, and his complacency generated widespread mockery in popular culture and a loss of respect in gentlemen's circles.
Edgar could have sued Heathcliff civilly for "damaging and trespassing on his property" (legally, the wife was considered the husband's property), but he chose not to do anything, which to society showed weakness and would generate a strong, veiled ostracism since it would be expected that he would take immediate legal action to clear the name of his class.
The fact that Edgar cut ties with the community and abandoned his position as a magistrate, which had given him social prestige, suggests he became a laughingstock.
This also explains why he isolated his daughter from everything to prevent her from learning about her mother and being ridiculed and ostracized in the community.
