Explain why Pip feels disappointed as he leaves Miss Havisham's house.

Pip has recently learned the true identity of his benefactor. For years, he'd always assumed it was Miss Havisham. For her part, she had done absolutely nothing to disabuse him of this notion; indeed, she positively encouraged it. It was all part of Miss Havisham's little game to toy with her greedy relatives, to make them jealous by giving the impression that she favored Pip over them. Pip feels like a fool, feels like he's been used—and he has. It's not surprising, then, that he's so thoroughly disappointed with Miss Havisham. Worse still, he's emotionally crushed, devastated by the cruelty of Estella, who's also been playing her own little games, toying with his affections. Estella has learned well the lessons of her mistress, as she was always intended to.
