De Botton also examines the role of fantasy and idealization in romantic love. He argues that our tendency to idealize our partners and relationships is a fundamental aspect of the human experience of love. However, he also suggests that this idealization can be a source of trouble, as it can lead to disappointment and disillusionment when reality fails to live up to our idealized expectations. De Botton contends that a more realistic and mature approach to love involves acknowledging and accepting the imperfections and limitations of our partners and relationships.
