Then, while staying at the Thrushcross Grange estate, Catherine made friends with Edgar and Isabella Linton.
After Edgar falls in love with Catherine, Heathcliff becomes irritated. She explains her feelings for both men to Nelly Dean, who is torn between her old buddy and the new friends she has made. In fact, as a result of their conversation, Heathcliff was able to hear everything. He was dissatisfied and decided to depart Wuthering Heights. After that, Heathcliff did not appear at the manor for years.
