Final answer:
Tomas's way of living, characterized by emotional detachment and casual relationships, makes Tereza feel insecure and emotionally tormented. Despite Tomas's love for her, his inability to commit solely to her causes significant emotional pain for Tereza.
Step-by-step explanation:
In Milan Kundera's 'The Unbearable Lightness of Being', Tomas's way of living significantly affects Tereza. Tomas lives a life of lightness, characterized by emotional detachment and numerous casual intimate relationships. In contrast, Tereza seeks depth and seriousness in life and love, which creates conflict between them.
Tomas's lightness of being leads Tereza to feel insecure and emotionally tormented. Despite his love for Tereza, Tomas's inability to commit solely to her and his continued affairs inflict massive emotional pain on her. Tereza's suffering is an essential part of her character development, and Tomas's lifestyle is the catalyst for this.
