What was the relation between mr and mrs wormwood in Matilda?

In Roald Dahl's children's novel "Matilda", Mr and Mrs Wormwood are described as uninterested and neglectful parents. They are more concerned with their own selfish interests than with the well-being of their daughter, Matilda.

Mr Wormwood is a narcissistic used car salesman who is greedy, dishonest and manipulative. He shows no affection or concern for Matilda and often mocks her intelligence and interests. Mrs Wormwood is a vain, self-absorbed former ballroom dancer who is only interested in her appearance and her social status. She views Matilda as a nuisance and rarely spends any time with her.

The relationship between Mr and Mrs Wormwood is characterised by a lack of communication, mutual understanding and respect. They often argue and belittle each other, creating a tense and unhappy atmosphere in the household. Matilda is the sole victim of their neglect, and she feels isolated and alone, longing for parental love and support.
