Sorry, this is only a short answer space. but hopefully this helps:
Pip makes clear in this chapter that, in general, he is not happy with his lifestyle. He is not happy with his state of mind, feeling guilty about Joe and Biddy, nor with his day-to-day life as a young gentleman about town. A symbol of the emptiness he feels with being a gentleman around town is indicated by his joining a men's club called "Finches of the Grove." The group meets over dinner, argues, and gets drunk and Narrator Pip does not respect the group of young gentleman enough to even introduce their names.
The only true friend Pip has met is Herbert, and Pip feels that he is betraying even that relationship by living the high life with a man who cannot afford it.
The chapter reinforces what the reader already knows about Pip: He has chosen a lifestyle which alienates himself from the people he loves, and even alienates him from his true self.
