Complete Change Over the Weekend

After Jane has run away from Thornfield, the book has taken a change for the worse. Its almost as if Bronte is meaning to confuse the reader. Here we are one moment where Rochester is toying with the passionate and independent Jane, then he asks her to marry him. She refuses, after finding Rochester's bizarre arrangement with his lunatic wife. What throws me off is that Jane scurries off in the night, which in fact is no way that Jane would go about leaving some situation she didn't want to be around. Jane's the character who stands up for herself and others. She gets sent to the "Red Room" for hitting her cousin because she was standing up for herself. She gets mad at Helen who just apologizes for not washing her hands, when in all reality she couldn't because the water had froze. And now she just sneaks off into the night, to be found begging for food the next day. But then she is found good company. I just don't understand the changes that undergo with in Jane's own mind, or to be more broad Bronte's mind. Hopefully the novel will get back into the groove that it was, when it was getting easier and easier to read.
