Mom-to-be Liv Abreu filled her Instagram account with happy pregnancy tidbits: A sonogram, a shot of her baby bump at 17 weeks, words of love to her unborn child.
The Bronx mom lost her baby, and nearly her own life, in a savage stabbing early Tuesday, with her live-in boyfriend slicing her up with a knife in their apartment near Yankee Stadium, cops said.
Abreu, 30, was stabbed multiple times in the chest and once in her side by berserk beau Oscar Alvarez, who fled and left his bleeding girlfriend to find help in a neighbor’s apartment one floor down.
Army veteran Abreu, an ex-paratrooper with the 82nd Airborne Division, survived — but their baby died as Alvarez stabbed his gal pal repeatedly, officials said.
Her brother, Juan Carlos Abreu, 42, said doctors expect her to make a full recovery.
“The physical wounds will heal,” her older sibling said. “The mental wounds will also heal at some point, but it will probably take longer. She’s positive. My sister, she’s a warrior.”
Alvarez surrendered to police about three and a half hours after the stabbing, and was charged with attempted murder, assault with intent to cause serious physical injury, assault and weapons possession.
He told police that Abreu was accidentally stabbed — seven times, sources said.
Abreu, in her seventh month of pregnancy, was thrilled by the prospect of welcoming her newborn, which a Facebook post indicated was a girl.
“She was so excited about the baby, both of them were,” said stunned neighbor Gloria Lambert, 52. “This was going be their first. She was showing. She seemed so happy.”
Abreu is recovering in Lincoln Hospital. The baby, who was due in August, died there, and Abreu was listed in critical but stable condition.
The victim’s Instagram pictures included her sonogram shot with the words “My little human.” Another posting read simply, “145 BPM’s” — heartbeats per minute — “The sound of love in its purest form.”
The couple was together in their third-floor apartment on Walton Ave. around 12:30 a.m. when Alvarez flew into a violent rage, repeatedly knifing his fiancée, officials said. He prevented her from getting help for half an hour as she bled out, then changed into a navy blue polo shirt and jeans before fleeing into the night, officials said. Alvarez, 30, surrendered around 4 a.m. to police at Transit District 11.
He initially took off in his girlfriend’s 2004 Jeep Cherokee, sources said. But the SUV was found abandoned just a block away, and cops recovered a knife from the bloody crime scene, sources said.
Alvarez’s Legal Aid lawyer, Joshua Hadas, described his client as a hardworking guy.
“He has no criminal history at all,” he said. “He has spent the last 10 years working at a local store where he has risen to the level of manager.”
Abreu served as a paratrooper and human resources specialist based at Fort Bratt, N.C., according to her social media profiles.
She graduated with a degree in political science and government in 2012 from the City University of New York. Abreu also served as a spokeswoman for the Iraq and Afghanistan Veterans of America, and helped CUNY veterans as a student assistant.
She is currently a T-Mobile retail store manager, and joined the company eight years ago as a sales associate. Neighbor Lambert said Alvarez often drove Abreu to their jobs at the Manhattan outlet.
“I feel so bad,” she said, shaking her head. “How could he do this?”
There were some indications on the victim’s Instagram feed of problems between the couple. “You can’t love him into deserving you,” read one quotation.
“Remember your value, remember you’re worth it,” read another.
Hilda Ramirez, 43, the victim’s sister-in-law, said she did not see a violent side to Abreu’s boyfriend.
“I know that they weren’t always getting along, but he didn’t seem like somebody who would be capable of doing something like that,” she said. “Not violent like that.”
