The French tourist whose neck was slashed by a stranger in Harlem on Valentine’s Day was finally on his way home Saturday, grateful that his attacker remains behind bars — and that he lived to tell the tale.

“American style: the bad guy sleeps in jail, I survived, I have the best sweetheart in the world, the best family, the best friends, I survived and I never felt so loved,” Gabriel Bascou wrote on Instagram.

“I can’t wait to come back to NY to discover this city that I saw only 100m between the place of my Airbnb and my attack.”

Bascou, 28, was ambushed on Day 1 of his dream trip, just as he and his girlfriend Manon Duma walked out of a breakfast date at IHOP on Adam Clayton Powell Jr. Blvd on Feb. 14th. Police say Khalief Young — known around the neighborhood for surprise stabbings — slashed without warning, sending the Frenchman to his knees, blood gushing on the sidewalk.

Bascou said he was “relieved” to finally leave Harlem Hospital, where he spent the past two weeks intubated and recovering from a tracheotomy.

He told The Post he’s still “déçu” he never got his chance to explore the City that Never Sleeps.

“My heart aches because since the attack took place the first morning I arrived, I didn’t see anything of New York,” he said.

The Parisian photographer and model is en route to Montpellier for more treatment, and said he’ll need several more weeks to completely heal.

A photo obtained by The Post shows the lovebirds cuddling as they wait to board their plane, a black bandana over Bascou’s horrific souvenir.

“Goodbye New York, goodbye injustice, goodbye to the hospital and to the medical team who supported and sustained us during all our moods, goodbye to the district attorney that helps us do justice,” Duma wrote from a lounge in John F. Kennedy airport.

A fundraising page has raised over $14,000 to help pay for Bascou’s medical bills — and the home-bound tourist says he “can’t wait to start eating and drinking again.”

“We’ve been literally flooded with love via social media,” Bascou said from the airport. “People seem to have been really affected by what has happened to us.”

Three days after the savage attack, cops busted Young, 28, who was kept locked up on attempted murder and assault charges. He was indicted last week and is expected back in court March 18.

The ex-con has a long rap sheet of violent attacks, including a June deli slashing where he allegedly stabbed a patron.
