Themes in Wuthering Heights?

The destructiveness of love that never changes is a reoccurring theme in Wuthering Heights. Catherine and Heathcliff’s passion for one another seems to be the center ofWuthering Heights, given that it is stronger and more lasting than any other emotion displayed in the novel, and that it is the source of most of the major conflicts that structure the novel’s plot. As she tells Catherine and Heathcliff’s story, Nelly criticizes both of them harshly, condemning their passion as immoral, but this passion is obviously one of the most compelling and memorable aspects of the book. It is not easy to decide whether Brontë intends the reader to condemn these lovers as blameworthy or to idealize them as romantic heroes whose love transcends social norms and conventional morality. The book is actually structured around two parallel love stories, the first half of the novel centering on the love between Catherine and Heathcliff, while the less dramatic second half features the developing love between young Catherine and Hareton. In contrast to the first, the latter tale ends happily, restoring peace and order to Wuthering Heights and Thrushcross Grange. The differences between the two love stories contribute to the reader’s understanding of why each ends the way it does.

The most important feature of young Catherine and Hareton’s love story is that it involves growth and change. Early in the novel Hareton seems irredeemably brutal, savage, and illiterate, but over time he becomes a loyal friend to young Catherine and learns to read. When young Catherine first meets Hareton he seems completely alien to her world, yet her attitude also evolves from contempt to love. Catherine and Heathcliff’s love, on the other hand, is rooted in their childhood and is marked by the refusal to change. In choosing to marry Edgar, Catherine seeks a more gentel life, but she refuses to adapt to her role as wife, either by sacrificing Heathcliff or embracing Edgar. In Chapter XII she suggests to Nelly that the years since she was twelve years old and her father died have been like a blank to her, and she longs to return to the moors of her childhood. Heathcliff, for his part, possesses a seemingly superhuman ability to maintain the same attitude and to nurse the same grudges over many years.

Moreover, Catherine and Heathcliff’s love is based on their shared perception that they are identical. Catherine declares, famously, “I am Heathcliff,” while Heathcliff, upon Catherine’s death, wails that he cannot live without his “soul,” meaning Catherine. Their love denies difference, and is strangely asexual. The two do not kiss in dark corners or arrange secret trysts, as adulterers do. Given that Catherine and Heathcliff’s love is based upon their refusal to change over time or embrace difference in others, it is fitting that the disastrous problems of their generation are overcome not by some climactic reversal, but simply by the inexorable passage of time, and the rise of a new and distinct generation. Ultimately, Wuthering Heights presents a vision of life as a process of change, and celebrates this process over and against the romantic intensity of its principal characters. 

There is a lot of people in society that claim to hate each other, when in reality they love each other. That is the only person they can be with, no matter the circumstance. In society there is always a destructiveness of love, more then half of marriages and relationships end in break ups or divorces, it is hard to find a "soul mate" or someone that is like you in a certain way that does not annoy you.
