Another Question!

When Pip goes to visit Miss Havisham and Estella for the very last time, he tells Estella that he loves her. But Estella's only response was that she was going to marry Drummle. She had no real reaction to Pip displaying his true feelings for her. Although, Miss Havisham felt somewhat bad for Pip. What I don't understand is why does Miss Havisham all of a sudden feel bad for Pip? She's the one who raised Estella to break a boys heart, and that's exactly what Estella did... so Miss Havisham should not feel bad for Pip, but yet she does.
