A woman who stabbed her husband with the knife she was using to make his sandwiches is beginning a three-year community rehabilitation order.
The court heard Keningale did not mean to kill her husband
The judge at Cardiff Crown Court was told Doris Keningale, 43, had suffered frequent verbal abuse.
German-born Keningale had previously denied the murder of her husband, Vincent, 61, but admitted manslaughter.
The court heard her husband was a "Jekyll and Hyde" character, and had refused to seek counselling.
The court was told she had not intended to seriously hurt her gardener husband when they started arguing about her plans to launch a jewellery business.
The prosecution accepted that Mr Keningale had been verbally abusive. On the night of the stabbing, Mr Keningale, was sitting on a stool in the kitchen of the couple's home in Risca, near Newport, south Wales. He had been drinking and was shouting at his wife.
Keningale suffered 'intolerable' abuse, the court heard
Keningale moved towards her husband, the court was told, intending to slap him to stop him shouting, but her husband laughed.
That was when she picked up the knife, which she had been using to make her husband's packed lunch.
The court heard Keningale turned towards her husband, holding the knife, and he stood up and moved towards her.
The knife, which had an eight-and-a-half blade entered his chest. She had not meant to seriously hurt Mr Keningale, the court heard.
Keningale was said to have been "hysterical" while dialling the emergency services. Her husband was later pronounced dead in hospital.
She later told police: "I did not want to kill him. I just wanted to say: 'Please stop'. He was so aggressive I could not cope any more. It was a cry for help."
The court heard that the couple were both Cliff Richard fans and had met at one of his concerts in Usk in 1991. Mr Keningale had worked as a bodyguard to the star.
The husband was described as a "Jekyll and Hyde" character, and had refused counselling. His wife had asked him to seek medical help for mood swings and forgetfulness.
Keningale had told the court that mental abuse was worse than if she had been abused physically.
Ieuan Morris, prosecuting, said the couple had few friends and Mr Keningale did not encourage his wife to socialise, and had used "cruel" words.
He said it was "a very sad, cruel background, where the verbal abuse was intolerable".
The court heard that the couple were both "avid" Cliff Richard fans and had met at one of his concerts. Mr Keningale had once worked as the singer's minder.
Photos had been taken in evidence, including ones of memorabilia relating to Sir Cliff, said Mr Morris.
Peter Murphy, in mitigation, said: "This is as close to an accident as it is possible to come."
He said his clients remorse was genuine and heartfelt and she remained in love with her late husband, but displayed features of "battered wives' syndrome".
Sentencing her, Judge John Griffith Williams QC said: "You were truly and genuinely shocked by what happened."
She gave her a three-year community rehabilitation order.
