why did penny and leonard break up in season 3
Leonard Hofstadter In the third season premiere, Leonard and Penny finally started a romantic relationship and had intercourse for the first time.[29] However, the relationship ended after eight months,[30] after Leonard told Penny he loved her and took umbrage at her inability to reciprocate, which led to friction that was exploited by guest star Wil Wheaton who appeared as a fictionalized version of himself, who observed and exacerbated it in order to break them up in the middle of a bowling match Wheaton's team was having against Leonard, Penny, Sheldon, Howard and Raj.
