(CNN) -- Jason Priestley played Brandon Walsh on "Beverly Hills 90210" from 1990 to 1998. Having long since hung up his Peach Pit uniform and Beverly Hills Beach Club cabana boy polo shirt, his character became a journalist and departed to take a job at the Washington Bureau of the New York Chronicle, and Priestley left the show four episodes into the series' ninth season. 

"I felt that the character of Brandon had kind of run his course. I had explored everything I wanted to explore with him," Priestley told CNN while promoting his new book, "Jason Priestley: A Memoir" (HarperOne) at the New York Bureau of CNN. 

"In retrospect, I do regret leaving. Understanding what I do now about story and character, I believe that [Aaron Spelling] was pushing the story in a direction that would have had Brandon and Kelly end up together at the end of the show and I think I probably should have stuck around to its fruition." 

Fans of "90210" surely remember Kelly Taylor's (Jennie Garth) "I choose me" speech following Brandon and Dylan McKay's (Luke Perry) showdown for her affections. Brandon wanted Kelly to marry him. Dylan wanted to take her on a trip around the world. But Priestley believes Executive Producer Aaron Spelling had always envisioned Brandon and Kelly riding off into the sunset. 

"I think my departure also hurt Aaron's feelings," continued Priestley. "Aaron and I had worked very closely together for a number of years. He gave me a lot of opportunities, and I feel like my departure hurt his feelings and I never meant to do that."
