O'Neal tells NBC's "Today" show that doctors said Fawcett had a couple of hours left, but she held on for a couple of days.
He says Fawcett's eyes were open for the last three weeks of her life. He thinks she was "holding on," since she had so much left to do.
Finally, he says, Fawcett closed her eyes and she was gone.
Fawcett, the pinup icon and "Charlie's Angels" star, died of cancer June 25 at age 62.
O'Neal says he writes to Fawcett in his journal, fulfilling a promise he made to his longtime love.
