Patrick Swayze's wife of 34 years walked out on the late actor in 2001 because she couldn't stand the Dirty Dancing star's boozy ways.
The star and Lisa Niemi split for almost a year as Swayze attempted to control his heavy drinking.
The actor has revealed the low point of his long romance with Niemi in his new memoir The Time of My Life, which hit stores on Tuesday (29Sep09).
He says, "I started drinking again... (and) I found levels of bottom that I didn't even know existed, but, for Lisa, this was too much.
"She packed up a couple of suitcases and took off one morning before I woke up."
A private memorial service for the actor will be held on 4 October (09) at Sony Studios in Los Angeles.
The actor's mother, brother Donald and wife Lisa Niemi are expected to attend the exclusive get together.
Fans are asked to make donations to either The Patrick Swayze Pancreas Cancer Research Fund or Stand Up To Cancer in lieu of flowers.
Swayze lost his cancer battle on 13 September, aged 57.
