"Pete met Kim Darby when they costarred in Generation. They dated steadily and some say Pete never got over his love for the wide eyed, popular actress."
Reportedly, Peter was shocked when Kim broke it off with him, telling him she was marrying actor James Westmoreland (formerly known as Rad Fulton) who she had only known for a few weeks. Darby and Westmoreland's marriage only lasted two months, and Darby reportedly tried to reconnect with Pete, but he had already begun dating Dianne Ray. Reportedly, he was deeply hurt by Darby's betrayal and all the press coverage he got for being dumped.
