Maylea Tinecheff tells Sunday Night that Ben Cousins ‘will die’ unless he can beat drug addiction

Ben Cousins’ former partner Maylea Tinecheff says she fears he will die unless he pulls himself out of his drug spiral.

"It’s got to a point now, where if this continues on, Ben will die, and his children need him," she says.

In a raw and frank interview to air on Channel Seven’s Sunday Night, Ms Tinecheff says Cousins had chosen drugs over her and their two children.

"To be a parent you can’t just love your child," she says.

"Love’s about sacrifices, you have to do what’s right for them. He’s chosen drugs over everything."

The Brownlow medallist is serving a one-year prison sentence at Acacia Prison after he pleaded guilty to stalking and repeatedly breaching a violence restraining order taken out by Ms Tinecheff.

"I know he’s in a lot of pain," she says in the interview. "I know that he’s humiliated by what’s gone on.

"Certainly I know he’d be sitting in there thinking he’s probably hating me to bits; in there thinking that I’ve done this to him but the drugs have destroyed him.

"He’s a broken man. It’s very sad."

The couple have two children, aged three and five, who have not been told their father is in prison.

Cousins’ battle with methamphetamines, which destroyed his football career, has been splashed across the headlines. But Ms Tinecheff reveals it was much worse than people knew and much was kept secret from the public.

When asked if Cousins’ purchased his drugs or had them given to him by others, Ms Tinecheff says she is "sure it’s both".

"It wouldn’t be hard for him to get drugs. Everyone wants to do drugs with Ben Cousins," she says.

In a series of bombshell revelations to air Sunday night, she reveals the real story behind the former West Coast Eagles captain’s arrests, including his bizarre behaviour outside a Sikh temple in Perth and how he ended up at a brothel in Esperance after he tried to smuggle drugs into a rehab facility.

The program will also air confronting never-before-seen private videos and photos of Cousins’ downfall and attempts by him and those around him to stop his addiction.

"Look, nothing was ever about me or how I felt about things," she says. "There was all sorts of things I had to put up with ... the drugs, the women, football, the lot."

Ms Tinecheff says the fallen AFL star, who will be eligible for parole in August, doesn’t realise the extent of his problem.

"He doesn’t get how unwell he is," she says.

"He’s so used to getting his own way ... he just doesn’t understand it."

She reveals what led to the restraining order and how she still loved the father of her children. She also addresses her own past drug use but insists she is now clean.

"I’m so pleased that they’re away from my life," she says. "It was the worst part of my life. I definitely wasn’t part of the problem. All that’s been said about me is bad stuff. It’s a shocking drug.

"When you first have it, you feel like you’re King Kong. But it quickly takes you on a downward spiral ... all the lies and manipulation that you lose the person that you love.

"When we were first together it was all recreational, and he’d stop when he had to play football. He blew me away how disciplined he was."

Ben and Me: The Downfall of a Football God airs on Sunday Night at 8.30pm on Seven.
