"One of these days," she said, "I'm going to pull myself together for a while and think--try to determine what character of a woman I am; for, candidly, I don't know. By all the codes which I am acquainted with, I am a devilishly wicked specimen of the sex. But some way I can't convince myself that I am. I must think about it." (27.4)
Edna understands that society would condemn her as a terrible woman, but she doesn’t view herself as a bad person. There’s an external/internal mismatch that Edna hopes to one day reconcile.
Quote 5
"You have been a very, very foolish boy, wasting your time dreaming of impossible things when you speak of Mr. Pontellier setting me free! I am no longer one of Mr. Pontellier's possessions to dispose of or not. I give myself where I choose. If he were to say, 'Here, Robert, take her and be happy; she is yours,' I should laugh at you both."
His face grew a little white. "What do you mean?" he asked. (36.42 - 43)
Edna declares that she is not a possession (which actually contradicts Louisiana law at this time). Edna asserts that she alone has the power to give herself (her love, her time, her company, etc.) to someone. Robert clearly doesn’t understand this concept.
Quote 6
"Coming back to dinner?" his wife called after him. He halted a moment and shrugged his shoulders. He felt in his vest pocket; there was a ten-dollar bill there. He did not know; perhaps he would return for the early dinner and perhaps he would not. It all depended upon the company which he found over at Klein's and the size of "the game." He did not say this, but she understood it, and laughed, nodding good-by to him. (1.17)
Mr. Pontellier is under no obligation to answer to his wife. He does as he pleases.
