Former Mets great Dwight Gooden has admitted for the first time that he needs help battling the drug and alcohol addictions that have gotten the better of him for decades, according to his ex-wife, who said it was those demons that split up their marriage.

“Monique, I’m tired,” Monique Gooden, 48, told The Post that the former ace said to her following his arrest Monday in Newark, New Jersey, for allegedly driving under the influence, the wrong way, on a one-way street.

“He actually told me that he’s tired and needs help,” she said. “He’s never said that. People who are in recovery or use drugs, they tend to be in denial. He actually said ‘Monique, I’m tired.'”

His second ex-wife said Dwight’s seven children are “rooting for him” to get help after he was arrested for the second time this summer.

Just last month, the former baseball great known as “Doc” was also busted for DUI and cocaine possession when cops in Holmdel caught him driving erratically and discovered drugs in his vehicle.

“He’s retired. He should be enjoying himself. He should be taking trips and spending time with his grandkids. We don’t want to see this” said Monique Gooden, who now lives in Columbia, Maryland.

She said that she believes that he’s finally kicking his demons for good — but “he’s going to have to put all that behind him and focus on him.”

“He needs to get himself well,” Monique told The Post. “He is going to have to be around people who are doing the same thing as him, which is hard.”

Monique — who shares son, Dylan, 14, and daughter Milan, 7, with him — divorced the once-legendary pitcher in 2013.

Despite weathering his numerous DUIs and scandals, she still remains by her ex’s side.

“Whatever support he needs, we’re here for him.”

“We got divorced because of this issue — absolutely no other reason because when we got divorced, I still loved him,” she told The Post.

Unable to pinpoint what exactly provoked his recent woes, Monique said: “He’s very hard working. He’s always giving. People are always asking him for his stuff. They’re always asking him to do favors but no one is really giving to him.”

Throughout all his troubles, she notes that fans have continued to support the star.

“The thing is all of the stuff he’s doing, the fans love him,” she said. “I’m just like wow he’s been through this all of this stuff and your fans really love you — and it’s because he’s a good guy.”
