In the book "Perfect Chemistry" by Simone Elkeles, the author explores the emotional complexities involved in ending a relationship. The protagonist realizes that breaking up in person can be incredibly challenging due to the immediate reactions and emotions of the other person. Witnessing their hurt and anger can add an overwhelming pressure that is difficult to handle.

This understanding sheds light on why some individuals choose to break up through less personal methods like emails or texts. It allows them to avoid directly facing the emotional turmoil and discomfort that comes with confronting someone else's feelings head-on.
