Gardner's wife, Maurice McCabe, says she is afraid her husband will be killed for false allegations of sexual assault.
Mr. McCabe, who formally left the force last month after he was corroborated by a survey of corruption, said the charges had "completely changed" his family life.
During an interview with RTE, former Sergeant Garda recalled the moment he heard of the charges and how she told him.
"We put all the kids in bed and I told Lorraine in the living room and I broke," he said. "She hugged me and she cried, so I told her."
Lorraine McCabe said, "I knew it was bad, but it did not make sense, I was afraid she would take her own life."
Mr. McCabe, who faced unjustified and false accusations of sexual assault, was voted in Charleton's report last month.
The Disclosure Tribunal found that former Commissioner Martin Callinan of Garda was part of a "criminal campaign" against Mr McCabe, who was assisted by a former press officer, Chief David Taylor.
Mr McCabe said the accusations of a girl, known as Mrs D, "have completely changed our family life altogether."
"I have never bought children or washed them," he said.
"I would not be here if the visitors had their children, I should always do something or go somewhere."
After investigating the charges, the file was returned from the Director of the Prosecutor's Office.
"What really stood out was that there was no case of sexual assault or any attack, and I think it was key. It was no crime."
In an interview with RTE on Monday night, Mr McCabe said that if he knew from the outset of the abuse he would suffer from raising the cover of Gaza corruption, he would "never do it".
The father of five, who joined An Garda Siochana in 1985, took up the role of Sergeant in Bailieborough in Co Cavan in 2004.
This was where he filed complaints about police standards in strength.
Ultimately, this led to his resignation as a sergeant-in-charge, and it was the beginning of a series of allegations against him.
Mr McCabe remembered how he became isolated and deprived of power as he simply did what he had deemed the right thing to do.
He said, "What I hoped was that the questions I said would be investigated and that I would return to the position of an assistant, and they would say yes, I was right to highlight these issues.
"If I had to know what was waiting for me, I would never have done it."
Mrs. McCabe said she was afraid of "getting into deep water."
"He just pushed things too far," she said. "It would not be me, I would leave."
In a two-part document, Mr. McCabe and his wife also describe in detail how he was the victim of online abuse in the form of "obscene" photographs of former colleagues from Garda on social media sites.
They said they realized the photos of the plastic rats that had been released by the arrows outside the operating guard were published online with the name written below.
Mr. McCabe said: "They had a plastic rat and showed them that they hit the darts, and also showed obscene sexual gestures with rats, and under the photo was the word" Maurice. "
"Then came the comment" strange rat bastard. ""
Mrs. McCabe, who described photographs as "ugly" and "terrible," said they gave them signs of the level of hostility her husband had encountered.
"It just gave us the feeling we had a feeling for him," she said.
"I remember I was across the road and I came home one afternoon when I went after the raid and I think," God, it's like a beautiful house, the gardens are beautiful, everything looks nice, you know, it was inside. "
The couple's marriage has also become the target of Garda's reputation.
"My colleague at Cavan Monaghan, he called me to say it was a reputation for leaving my wife," recalled Mr. McCabe. He told me exactly who said the reputation (Garda).
"After a few days I met him, I saw him on the street, pulled him out and told him," I did not leave my wife "and said," Oh, somebody came to the station and told me. "
"I said," You should have checked it before you spread it. ""– Print the association
