A Sydney man has been found guilty of murdering his wife by setting her bedroom on fire after she told him their marriage was over.
The man, who can only be referred to as AKB, showed no emotion when the jury foreman delivered the guilty verdict in the NSW Supreme Court.
Justice David Davies acknowledged the trial has been stressful for the jurors and offered them counselling.
During the trial, the court heard he set his wife's Guildford bedroom on fire in 2016 after she met another man on social media messaging app Viber.
The court heard petrol was used to start the fire and the man pushed his wife into the flames as she tried to escape.
The jury heard evidence the couple fought during the fortnight before the blaze.
Crown Prosecutor Christopher Maxwell said the woman told the man she no longer wanted to live with him in various messages.
"I am tired of you, that is it," she wrote on one occasion.
"If you talk or raise your hand on me you know what I'll do, I have cut off living with you."
The jury heard the home very quickly became an inferno.
After police and firefighters arrived, the man told detectives the fire was started by a heater and claimed he had tried to rescue his wife.
A neighbour saw the woman at a window screaming "help me" and the court was also played a triple-0 call made from the home.
The victim was 18 when she married her then 35-year-old husband.
The man will be sentenced at a hearing in September.
