Over the years he disclosed the abuse by Joyce to family and friends - he was feared for his safety and he wanted to end the relationship but he was too ashamed to ask for help.
On December 29, 2020, the pair argued - according to Joyce - and she took to Berry with a kitchen knife.
She stabbed him repeatedly in the neck and cut his throat.
She dragged his body out of the house, out to the compost heap and covered him with rotting food and leaves.

For two weeks she stayed at the house, cleaning the scene of the crime and clearing all of Berry's belongings.
She claimed to have been sober for 17 months but relapsed into drinking. Heavily.
Then on January 12, 2021, she turned herself into the police and made a full confession.
Joyce claimed Berry's death was accidental but was found guilty of murder and sentenced to life in prison by Justice Jonathan Eaton in May 2022.
In this episode of Herald podcast A Moment In Crime, senior journalist Anna Leask delves into the case and explores what happened and why.
Leask reported on the initial homicide investigation and then followed Rena Joyce's case through the courts until she was sentenced in May 2022.
A Moment In Crime is written and hosted by Leask - who has been covering crime and justice for NZME since 2005.
Leask has also reported on most of the major incidents and events in New Zealand during that period including the Christchurch quakes, Pike River mine disaster, March 15 terror attack and the White Island eruption.
"Each month I'll take you inside some of our most infamous incidents, notorious offenders and behind the scenes of high-profile trials and events to show you what's really happening in your backyard," she said.
"Heroes and villains battle for justice to be done, and it seems no matter how horrifying the story, we always want to know more.
"If you want to know more about the cases that have shocked and shaped our nation - from murders and massacres to violent villains and the utterly unbelievable - join me for A Moment In Crime."
In our first episode, we looked back at the Christchurch terror attack - what unfolded on March 15 and how it changed New Zealand.

In 2017, Leask wrote and hosted Chasing Ghosts - a six-part podcast series on the Amber-Lee Cruickshank case.
The South Island toddler disappeared almost 27 years ago from a small town on the shore of Lake Wakatipu.
Despite exhaustive and repeated searches, there has never been any sign of the little girl.
To mark the 25th anniversary of Amber-Lee's disappearance, Leask investigated the famous cold case in a bid to generate some answers for the toddler's family.
It was the Herald's first true-crime podcast.
