Books like Emily Brontë: Wuthering Heights: Critical Studies

I had heard for years the reference to Kathrine & Heathcliffe linked in the category of romance couples. I watched the Laurence Olivier movie and cried at his loss. Then I read the book. I was appalled at the way Katherine treated Heathcliffe! Then I discovered that most movies only end with Katherine's death which is not the end of the story, it's the middle. Heathcliffe is a horrible human being! He may be pining away, literally insane with the loss of Katherine, but they way he treats the people he is in charge of (including Katherine's own daughter) is not enjoable to read! I have determined that the Bronte sisters must have had horrible, depressing, abusive lives for all they've written. I'll stick with my tried and true Jane Austen for true romantic couples.
