After Arobin leaves, a variety of emotions overcome Edna.
She feels like an irresponsible wife.
She feels guilty thinking about Robert, whom she really loves.
She feels that she can suddenly comprehend what life is about more clearly than she had before.
But even with all these conflicting emotions, she feels no shame or remorse, only a little regret, because her first truly passionate experience had been with a man (Arobin), for whom she feels no real love.
