A man who repeatedly stabbed his partner of 34 years after she ended their relationship amid an affair with another man has been jailed for six years and nine months.
Kim Ashley Prunster, 57, stabbed Amanda Gibbons, 52, up to 14 times while she slept at their home in Dongara, in the state's Mid West region, in November 2017.
The kitchen knife he used inflicted life-threatening injuries, piercing her lung and causing abdominal bleeding, but she survived after major surgery.

The Supreme Court of WA heard Ms Gibbons had been having a relationship with the proprietor of the pub where she worked but once that emerged, she and Prunster met with the man and his wife, and they agreed to end it.
Ms Gibbons and Prunster, who have four children and seven grandchildren, later argued after he saw text messages on her phone that revealed the affair continued.
She told Prunster their relationship was over and she planned to move out but he wanted her to stay.

Prunster told the court he asked her for a hug and she replied: 'Why? It won't mean anything.'
As she slept, he knelt by the side of their bed holding the knife.
She told the court she awoke to see him with a 'weird' expression and vacant eyes.

During the attack, she told him to stop, at one point saying: 'I'm dying'.
He then sat on the edge of the bed crying, saying he was sorry, before leaving the house without calling for help as she'd asked.
Prunster phoned Ms Gibbons' lover, saying he'd better call an ambulance and asking him to look after a son who still lived at home.
He then drove to a bush track and tried to take his own life.
Justice Stephen Hall said he did not accept - and neither did the jury after a five-day trial earlier this year - that Prunster was in a dissociative state.
Rather, he was overwhelmed by anger, stress and the feeling his life had been destroyed.
'You came to realise there was no hope of a reconciliation,' Justice Hall said.
Prunster had previously told the court he couldn't remember attacking Ms Gibbons, according to the ABC.
He said he remembered holding a bloodied knife.

'I don't know what happened. Her face came into focus and she was crying and saying ''please don't hurt me anymore'',' Prunster said.
Justice Hall accepted Prunster was remorseful and made him eligible for parole after serving four years and nine months.
The jury acquitted him of attempted murder but found him guilty of grievous bodily harm with intent.
