In section three of The Metamorphosis how do his concerns change?

As the story continues, we see that Gregor, in his transformed
state, becomes more and more withdrawn and disengaged from his family and more and more
preoccupied with his own concerns and wants. Even though he is aware of what his family is
suffering, and dreams about asserting himself like he did to "take over the family's affairs," he
does nothing, and instead becomes more and more isolated from his family, only serving to look
upon them and their increasing difficulties as a voyeur would rather than being active and
engaged in the problems his family is facing. The "bony charwoman" who is employed to look after
the house (and, by default, Gregor), is not disgusted by him and it is clear that she would
happily crush him if he gave her an opportunity. The narrator tells us that Gregor hardly sleeps
at all, and that he begins to eat "next to nothing," only playing with a bit of food in his mouth
before spitting it out. We can see that his primary concern is his new position in life as a
hidden outcast whose existence is barely tolerated and who is ignored and repulsive to those he
once loved.
