Fair enough, Laura. I enjoyed reading "Jane Eyre" myself, and Rochester's attic may have been preferable to Bedlam(although I still don't see why Rochester kept his wife's existence a secret). Also, both authors were the daughters of Anglican clergymen. I wonder if Charlotte Bronte was mocking St. John's Puritanism (Austen was clearly mocking her cleric, Mr. Collins). I will continue to think that Rochester was, if not abusive, at least close to it. He tells Jane (while dressed as a gypsy) that he is going to marry Miss Ingram and later excuses his lie by saying he wanted to make her jealous. That's a minor sort of abusiveness.
If you didn't like "Pride and Prejudice", you probably wouldn't like Mansfield Park. Austen's style remains the same, although the circumstances of her heroine are close to Jane Eyre's.
Also, I don't think Rochester is thinking of himself when he uses his pet names for Jane. Instead, he is betraying his subconscious by choosing the names he does.
