Do the characters seem real and believable?

The characters in The Edible Woman seem real and believable. I think this because the character Marian is a normal woman, she is working, has a boyfriend, and living in an apartment with her friend. Her boyfriend Peter states she is smart and realistic, "you're such a sensible girl"(pg.100). She has many emotional rollercoaster’s throughout the novel, similarly to a real woman. She struggles with relationships, and self confidence. Peter seems real and believable because he has a significant amount of pride in himself, which is understandable because he is in school to become a lawyer, which makes him think he is the better than everyone. He knows Marian's job at market research film is not as important as his job will be, so he acts more confident. The character Clara also seems real and believable because she is a mother of three children, married to her husband Joe. She had to drop out of college because she became impregnated with their first child, which can relate to many women. Clara has no social time because of her children, "Clara has so few people she can really talk to"(pg.36). this is very believable as well. All these characters resemble somebody I know of in my life, which make them seem real and believable.
