Jane from an early age developed a strong sense of identity and independence. With this true knowledge of self, Jane was able to face all turmoils in her life. No matter how new, and confusing the situation, she did what she, and only she believed was best. "I am no bird, and no net ensnares me; I am a free human being with an independent will." (Bronte ch.23) This attitude however causes her to run away from Mr. Rochester after she learns of bertha, for she realized how ready she was to be completely devoted to him in marriage, which scared her. She had spent so much of her life fending for herself, and not accustomed to happiness, that she couldn't believe Mr. Rochester's love was to good to be true. There had to be something wrong. This thought is over turned however in the end for Jane realizes true happiness can be possible. That love is possible. She follows her heart, but still remains independent, and therefore finds true happiness in the end.
