Catherine grows close to Heathcliff, and they fall in love. However, Catherine marries another, the tranquil and considerate Edgar Linton, the heir to Thrushcross Grange. She chooses social standing rather than a relationship with Heathcliff because of this.
Despite her love for Heathcliff, Catherine gives up her freedom to marry Edgar Linton. After the wedding, Catherine moves in with Nelly at Thrushcross Grange. Edgar passes away shortly after their marriage.
As a result, Heathcliff regains control of Wuthering Heights and Thrushcross Grange. He also makes it impossible for Catherine to leave Wuthering Heights by making her serve as a housekeeper there. Lockwood sells the estate to him instead.
In Chapter 9 of Wuthering Heights, Catherine tells Nelly that Edgar Linton proposed to her. She explains that she accepted the offer. The female also extols Heathcliff’s virtues.
However, she adds: “It would degrade me to marry Heathcliff.” These are precisely the words he hears. Following this, he decides to leave Wuthering Heights for three years. Catherine then marries Edgar.
In the book, Catherine spends five weeks with the Lintons at Thrushcross Grange in the novel’s early sections. According to Catherine, Mrs. Linton influenced her to become a high-class lady with excellent manners.
Wuthering Heights deteriorates considerably after she returns. The idea that Hindley and his pals had altered things was well received by the rest of the community. Heathcliff was the only person who saw matters going downhill for him as a result of these changes.
He understands that Cathy is no longer the wild girl he once knew. She has evolved considerably from the young lady he used to play games with throughout the heather fields. In contrast to Heathcliff, Edgar is a nobleman. He’s nice and considerate. Catherine also changes as a result of Edgar and his family’s influence. She becomes more vocal in her criticism of Heathcliff for his stupidity.
Despite her affection for Heathcliff, the lady decides to marry Linton. She has long-held aspirations of using Edgar’s money to save Heathcliff from Hindley’s tyranny. Heathcliff considers her desire a betrayal.
When he overhears Nelly discussing it, he leaves Wuthering Heights immediately and in great anger. Catherine is sad at first, but she eventually marries Edgar and moves into his home at Thrushcross Grange.
The error leads to Cathy’s sickness, madness, and death. It also transforms Heathcliff into a demonseed. He vows to wreak havoc on everyone who was involved in his downfall by any means necessary.
