why couldn't isabella stay at the Grange? what caused her to hate heathcliff?

Isabella berated Heathcliff unmercifully for his actions, particularly his uselessness and grief which resulted from Catherine's death. After demeaning him at the breakfast table and condemning him for his misuse of Hindley, Heathcliff threw a knife at her, and she fled, knocking down Hareton, "who was hanging a litter of puppies from a chairback in the doorway” (183).
