Love vs. autonomy

 Jane maintains her independent spirit, growing stronger in her beliefs and ideals with each conflict; Jane's inferior position as a governess serves simply to heighten her thirst for independence, both financial and emotional. She rejects marriages to both Mr. Rochester and St. John because she understands she will have to forfeit her independence in the unions. Only after she has attained the financial independence and self-esteem to maintain a marriage of equality does Jane allow herself to marry Mr. Rochester and enjoy a life of love.
