One of the most striking examples of a troubled marriage in the novel is that of David's parents. Mr. and Mrs. Copperfield are ill-suited for each other from the start, and their relationship is marked by conflict and unhappiness. Mrs. Copperfield is a cold, distant woman who is emotionally neglectful of her son, while Mr. Copperfield is a weak and ineffectual man who is unable to provide for his family. Their marriage ultimately ends in divorce, and David is left with a lasting sense of loss and abandonment.
Another unhappy marriage in the novel is that of Mr. Murdstone and his second wife, Dora. Dora is a young, naive girl who is completely unprepared for the responsibilities of marriage. She is frivolous and extravagant, and she quickly falls into debt. Mr. Murdstone is a harsh and domineering man who treats Dora with contempt. Their marriage is a disaster, and Dora eventually dies of consumption.
In contrast to these unhappy marriages, Dickens also portrays some positive examples of marriage in David Copperfield. One such example is the marriage of David and Agnes Wickfield. Agnes is a kind, intelligent, and compassionate woman who is deeply in love with David. Their marriage is built on mutual respect and affection, and it is a source of great happiness for both of them.
Another happy marriage in the novel is that of Peggotty and Barkis. Peggotty is a warm-hearted, hardworking woman who is devoted to her husband. Barkis is a gruff, taciturn man, but he is also kind and loving. Their marriage is simple and unpretentious, but it is filled with love and happiness.
Through these contrasting examples of marriage, Dickens explores the complex nature of this institution. He shows that marriage can be a source of great happiness and fulfillment, but he also warns of the potential for unhappiness and disappointment. Ultimately, Dickens leaves it up to the reader to decide what kind of marriage they want to have.
