“Terminator 2” kid star Eddie Furlong beat and abused his cradle-robbing girlfriend during the years they lived together, his angry ex charges.

Jackie Domac, who hooked up with Furlong on the “Terminator 2” set when he was 13 and she was 26, “was subjected to a barrage of verbal abuse, threats, violent outbursts [and] outrageous and unlawful attacks,” she charges in papers filed in Los Angeles Superior Court.

The unlikely pair met when Domac worked as Furlong’s stand-in in the 1991 Arnold Schwarzenegger megaflick.

They soon became inseparable, and Furlong, who was estranged from his parents and lived with an aunt, hired Domac to be his at-home and on-the-set school tutor.

The couple later moved in together – with Furlong’s family charging that Domac was a gold digger manipulating the millionaire teen star.

But the relationship endured until last October.

In the suit, Domac claims that last May, Furlong – now 21 – attacked her in their Sherman Oaks house, “throwing objects at her … screaming at her; rushing toward her and swinging his fists.”

Then, the court papers say, “Furlong pinned Ms. Domac down on the bed and began using his fists to strike her in and about the head,” the papers charge.

The documents, filed Friday, claim that other violent scenes had occurred before, and that Domac was “similar to a battered wife” and was afraid to tell police about the abuse.

Domac also says she worked for Furlong as his manager and she wants to be paid 15 percent of everything he made in the past three years, including his pay for the movies “Pecker” and “American History X.”

Her cut comes to at least $110,000, the suit says.

The young star’s ex also wants big bucks in damages for the “severe emotional distress” of putting up with Furlong for all those years.

Furlong’s publicist, David Luft, did not return a phone call.

Furlong was plucked out of obscurity by a casting agent who spotted him at a Pasadena Boys Club and asked him to audition for the part in “Terminator 2.”

At the time, he was living with an aunt, but his mother, Eleanor Torres, eventually went to court and regained custody of the new acting sensation.

Furlong fought back and had himself emancipated from his relatives, gaining the legal status of an adult in charge of his own affairs at age 15.

All along, he was close to Domac, but the pair always claimed they never had sex before he was 16.

“Jackie’s always been my backbone,” he told Cosmopolitan in 1996. “She goes everywhere with me, because otherwise we’d miss each other.”
