Many people in the world are trying to find a perfect companion.Some of these may marry and not know what their new husband or wife is like.This kind of situation often leads to separation or hostility. Other situations may develop between two friends that stem from jealousy, desire for revenge, uncaring parents, etc. Emily Brontë's Wuthering Heights displays several characteristics of destructive relationships. Three of these are uncaring parents, marriage without knowing the person, and jealousy.

　　Uncaring or unsympathizing parents are shown throughout this story to be an element of destructive relationships. Because Heathcliff gained all the attention from Mr. Earnshaw, Hindley became disassociated from his father. This separation continued until after Mr. Earnshaw had died.Another example is between Hindley and Hareton. Hindley became such a drunk and a gambler that he could not properly care for young Hareton. This led to a separation between Hareton and his father as well. One primary example of an uncaring parent is shown between Heathcliff and his son Linton.Heathcliff did not even want his son for anything except enacting a part of his revenge. This is shown by Linton's fear of Heathcliff and Heathcliff's enmity toward his son. Linton even says "... my father threatened me, and I dread him - I dread him!" to express his feeling about Heathcliff.The hostility and separation between father and son in this book shows that uncaring parents can cause serious damage in relationships with their children.

　　This element of destructive behavior may stem from an unhappy marriage in which the husbands or wives don't know each other. This had happened between Isabella and Heathcliff. Isabella did not really know Heathcliff when she married him, but after she had married him she saw that Heathcliff was not a gentleman at all. To declare her feelings she wrote "Is Heathcliff a man? If so, is he mad? And if not, is he a devil? I shan't tell my reasons for making this inquiry; but I beseech you to explain, if you can, what I have married ...". Another example of this is when Catherine married Edgar Linton. Although she had been happy at the beginning of the marriage, she thought having parties all the time was going to be fun. Yet, after a while, she became bored. She also realized that she loved Heathcliff more than Edgar and would always love Heathcliff.This enlightenment created separation between Edgar and Catherine during the final hours of Cathy's life. An additional marriage which was made that was doomed was the one between Catherine and Linton. Because this was a forced marriage, Cathy had not yet learned all she could about Linton.Because she did not know until after the marriage that Linton was selfish and inconsiderate, she became distressed and grew isolated in the house.These three failed marriages described in this novel show that knowing the person you will marry is very important.While these marriages took place, jealousy also took a hold in some relationships. One example of this is when Mr. Earnshaw starts to favor Heathcliff over his own son, Hindley. Because of this, Hindley becomes jealous of young Heathcliff and sets out to make Heathcliff's life a nightmare. Hindley's jealousy becomes evident when he says ,"... be damned you beggarly interloper! and wheedle my father out of all he has; only afterwards show him what you are, imp of Satan.". Jealousy was also found very notably in the relationship between Heathcliff and Edgar Linton.
