The director was asked to write a memoir about his time with the late singer, but has decided to keep his memories private, according to the Daily Star Sunday.
"Reg has had loads of offers to write a book about his life with Amy but he says it would be just too painful," a friend told the paper. "He also wants to keep as many of his memories with Amy completely private. (sic)
"He's making a film in memory of her but he won't start working on that for a while because it's all still too raw."
Winehouse was found dead at her her North London home in July. Her death was not drug-related and it has been suggested that her 'excessive' detox regime was the cause of death.
Traviss was said to be "in a really bad way" following his girlfriend's death and recently paid tribute to her on what would have been her 28th birthday.
Winehouse's father Mitch revealed last week that he is to publish a "heartfelt and revelatory" book next summer detailing her "incredible story in full". Proceeds from Amy, My Daughter will be donated to the Amy Winehouse Foundation.
"I feel that I need to write this book to tell the true story of Amy and to help with my personal recovery," Mitch explained. "I also want to raise as much money as possible for Amy's foundation, so all proceeds from the book will go directly to help children who are disadvantaged through illness and substance addiction."
