From the story "The Necklace" Guy de Maupassant: which word describes mme. Loisel life?

I'm not sure if you have choices, but some words you could use to describe her life are "simple", "plain", or "humble". Her life was fairly comfortable since she was born in the middle class, but to her, she believed it was horrible and dreadful that she wasn't part of the upper class. She was never satisfied with what her husband worked hard for and was a spoiled person in general.
