A young father-of-three was so heartbroken by the breakup of his family that he snuck out of a hospital and took his own life.
Brieze Montiero, 31, died alone is his flat in Perth on Monday having not seen his sons, aged 11 and 12, and nine-year-old daughter since Christmas.
'He felt like he had lost everything and was living a nightmare that was never going to end,' his grieving mother Beverley Bell told Daily Mail Australia.

Mr Montiero even sent a haunting series of late-night messages to his new girlfriend, Sarah Smith, two weeks before his death, giving her instructions for his funeral and begging her not to tell anyone he planned to kill himself.
His death highlights the heightened risk of suicide among men following relationship breakdowns.
Preliminary findings from new research by Griffith University indicate more than 60 per cent of male suicides can be traced back to breakups.
Ms Bell said her son's marriage ended a year ago when he returned home from his job on an oil rig.
'He worked extra to pay for a new pool for his kids. He got back on New Year's Day and she had his bags packed for him at the door,' she said.
'It crushed him. He tried to work on it, but not even a month later he tried to kill himself.'

Mr Montiero became despondent about how little time he was able to spend with his children as a result of his marriage breaking down
Mr Montiero survived that suicide attempt after days in the ICU, and after months of depression finally moved on and found love with Ms Smith in mid-2018 and began to enjoy life once again.
However, he became despondent about how little time he was able to spend with his children as a result of his marriage breaking down.
'He spiralled quickly from there,' Ms Bell said.
In January when he was working away he emailed his ex-wife to begin divorce proceedings as he had just signed a lease to move in with Ms Smith.
On January 28 he sent a series of alarming messages to Ms Smith declaring that he was going to kill himself after he returned and saw his children one last time.
'Once I say goodbye to my kids I'm gone, can't take the pain,' he wrote at 3.41am.
But he would never see his children again.

After Ms Smith sent Ms Bell the messages, the desperate mother spoke of her pain and fears for her son on social media.
'Parents of adult children who do have a suicidal child, my heart bleeds for you. The pain of waiting for the phone call is unbearable,' she wrote.
Mr Montiero got home on February 6 and on the morning of the day he died sent a series of messages to Ms Smith as if to say goodbye.
Ms Smith got increasingly worried and told him she would tell his parents what he was saying if he didn't stop and reassure her he wouldn't do anything stupid.
But Mr Montiero's last messages were even darker: 'I won't be sleeping tonight, not in this world. Sorry for ruining your life.'
Ms Smith contacted her boyfriend's parents and asked for help, after which Ms Bell called triple-0 and emergency services found him and took him to hospital about 10am.
Ms Bell, living 500km away in rural WA, pleaded with police and hospital staff to keep an eye on him, concerned he would sneak away and harm himself.
