​A woman who admitted she pulled the plug from her fiancé’s kayak and was “euphoric” as she watched him drown in the frigid Hudson River dodged murder ​and manslaughter ​raps Monday, taking a plea deal for the lesser charge of criminally negligent homicide.

Angelika Graswald, 37, who had faced 25 years to life in prison if convicted at trial now faces as little as 16 months ​to four ​years behind bars.

And with time served since her imprisonment in 2015, the slap -on-the-wrist sentence could see her released on parole as soon as December, her lawyer said.

The deal comes despite Graswald’s stunning statements to police, which a judge ruled could be admitted into evidence.

“I wanted him dead and now he’s gone,” she told cops during a lengthy 2015 interrogation.

“And I’m OK with it,” she added.

Orange Country prosecutors had charged her with second-degree murder and manslaughter, claiming she wanted to cash in on Viafore’s $250,000 life-insurance policy. He would have been her third husband.

The DA’s office said she cruelly “moved the paddle away from him as he was struggling to stay afloat with water temperatures in the 40-degree range, and failed to render him assistance, including timely calls for help.”

Asked during the 11-hour interrogation why she wanted Viafore to die, the Latvian immigrant bizarrely performed yoga poses and said, “I wanted to be free.”

She said their relationship had been strained ​when he pressed her for “sexual stuff,” saying, “He wanted threesomes, porn, everything.”

The missing kayak plug was eventually recovered from the center console of the car Graswald was driving, prosecutors said.

But she had maintained Viafore drowned because he was drunk — not because of the missing plug — and that she was just telling the cops what they wanted to hear to get out of a gruelling interrogation.

“I was at my breaking point. I just, I had it. So I just gave ’em what they wanted,” Graswald told “20/20” in 2015.

Graswald on Monday tearfully admitted that she pulled the pl​​ug from husband-to-be Vincent Viafore’s boat before watching him drown as his kayak capsized during a boozy boating trip in April 2015.

She said she knew that the ring for his paddle was missing, and that he was not wearing a life vest or a wet suit despite heading into dangerously cold and rough conditions, prosecutors say.

Both sides claimed victory in Monday’ plea deal.

“While no outcome can compensate for the loss [to Viafore’s family] this disposition will hopefully bring a measure of closure,” said DA David Hoovler. “This plea ensures that the defendant will be held criminally liable for her actions.”

Defense lawyer Richard Portale said, “We have maintained from the beginning this was not an intentional killing. This resolution supports that,” he said.

Graswald, whose US resident status expires next year, faces deportation back to Latvia, prosecutors added.

​Her sentencing is scheduled for Nov. 1.
