The boyfriend of an Israeli woman killed while attending the music festival stormed by bloodthirsty Hamas terrorists said he is living in agony after deciding at the last minute to skip the rave.

“I feel like I needed to go and be there with her. Maybe I could have done something different,” Ohad Malul said over the phone, his voice cracking. “It’s killing me inside that I am not with her.” 

Malul spoke to The Post from Israel on Tuesday when his girlfriend of two years, Shani Kupervaser, had not been seen or heard from since she fled the Tribe of Nova event in the Negev Desert. She and three friends were attacked by Hamas fighters with grenades and gunfire. 

“We don’t know if she is alive, dead or if she is missing. We don’t know if she is kidnapped because nobody told us,” Malul said at the time.

The next day, he got the devastating news. 

“We were just informed that Shani was not found alive and the terrorists murdered her,” he texted a Post reporter. 

His girlfriend is believed to be one of the 260 or more attendees who were killed by Hamas terrorists who paraglided across the border from Gaza and raided the event Saturday. 

Kupervaser — a 27-year-old economics student who had a job lined up for after graduation — went to the Nova festival with six friends, but Malul said he decided not to go since he was tired after just getting back from a trip to Paris.

“She said, ‘I will come back, I won’t go for long … Everything is going to be OK,’” he said.

But that quickly changed when Malul, also 27, received a message from his girlfriend saying she saw rockets overhead.

Kupervaser fled immediately with three friends in a car, heading toward her home in Be’er Sheva, but they came under gunfire and abandoned the vehicle to run into a roadside bomb shelter where people directed those fleeing to take cover.

It turned out to be a trap.

“They took 30 people inside and terrorists started throwing grenades inside it,” said Malul, recounting conversations he’s had with the friends who made it out alive.

A man inside the shelter bravely began catching the grenades and hurling them back out at the Hamas terrorists, and one of Kupervaser’s friends did the same.

“After five or six grenades, the terrorists got upset and got an RPG rocket and shot through the door,” Malul said.

They then went inside the shelter and “shot everywhere.”

Israel-Hamas war: How we got here

2005: Israel unilaterally withdraws from the Gaza Strip more than three decades after winning the territory from Egypt in the Six-Day War.

2006: Terrorist group Hamas wins a Palestinian legislative election.

2007: Hamas seizes control of Gaza in a civil war.

2008: Israel launches military offensive against Gaza after Palestinian terrorists fired rockets into the town of Sderot.

2023: Hamas launches the biggest attack on Israel in 50 years, in an early-morning ambush Oct. 7, firing thousands of rockets and sending dozens of militants into Israeli towns.

Terrorists killed more than 1,200 Israelis, wounded more than 4,200, and took at least 200 hostage.

Israeli Prime Minister Benjamin Netanyahu was quick to announce, “We are at war,” and vowed Hamas would pay “a price it has never known.”

The Gaza Health Ministry — which is controlled by Hamas — reported at least 3,000 Palestinians have been killed and more than 12,500 injured since the war began.

Kupervaser became separated from her friends at that point as thick black smoke filled the shelter, according to her friends’ accounts.

“It is something that you can’t imagine, them throwing grenades in a small room just to kill everyone,” Malul said.

“The other people who survived can almost not talk. They are devastated,” he said, adding that another one of her friends whom she fled with is missing.

On Tuesday, Malul said his girlfriend, whom he met at university, was not on any of the lists of the dead shared by Israeli authorities and hasn’t been found at any hospitals.

He said his only option was to hope that she’d been kidnapped if that meant she was still alive.

“I just hope that she is alive, that’s it. Just the hope,” Malul told The Post before he learned the tragic news. “If they take her from me, my heart is going to break totally.”

He said Kupervaser’s 28th birthday is in just a few days and that she was about to begin a job at a highly competitive company.

“She is the smartest, [most] beautiful, kindest person I ever met. Everyone who meets her falls in love with her,” Malul said. “She was one of the best in economics. She did two degrees in four years.”

He told The Post they had just bought new furniture together and he planned to propose soon.

“I just hope that she comes home. I just want to hold her and tell her that I love her so much. She is the love of my life. She is the love of my life … I don’t care what happened, I just want her to be there,” he said, his voice trembling. 

Less than 24 hours later, Malul got the news that Kupervaser never made it out.
