A girlfriend-from-hell faked a series of emails to rob her musician lover of his dream to study with one of the best professors in the world, according to a Canadian judge who ruled that she must now fork over $260,000 for ruining his life.

Eric Abramovitz, a talented clarinetist, had no idea he was being duped by Jennifer Jooyeon Lee, who hatched an evil plan so that he’d miss out on a highly competitive chance to study with professor Yehuda Gilad in Los Angeles.

The couple met while studying at McGill University’s Schulich School of Music in September 2013 and a month later, Abramovitz moved into her place, the National Post reported.

They grew so close that Abramovitz, who had won several competitions and was even featured on CBC Radio 2, felt comfortable sharing his passwords with Lee, a flutist.

Her secret manipulation began that winter when Abramovitz auditioned for one of just two spots for a two-year study directly under Gilad, who teaches clarinet at the Colburn Conservatory of Music.

After flying out with his parents for an audition in February 2014, Abramovitz was accepted for the full-scholarship study.

The plum offer was sent via email — which Lee craftily intercepted. Unbeknownst to him, she impersonated Abramovitz and declined the offer, saying he’d be “elsewhere,” before deleting the message.

Lee even created a fake email account — giladyehuda09@gmail.com — to pose as the professor and send Abramovitz a bogus email that offered him a different spot at the school and a more modest scholarship of $5,000.

She knew that without a full ride, Abramovitz wouldn’t be able to afford the world-class school. He wound up graduating from McGill and taking a less prestigious graduate certificate at the University of Southern California.

“She apparently did these things so that Mr. Abramovitz would not leave Montreal, and instead would stay in Montreal and remain in his relationship with her,” said Judge David Corbett of Ontario Superior Court.

The couple broke up in September 2014 for unrelated reasons.

At USC, Abramovitz was still under Gilad’s tutelage — but just for about an hour a week, far less time than he would’ve been afforded with the initial offer.

Lee’s deception was finally uncovered when Gilad asked Abramovitz, “Why did you reject me?,” according to the National Post.

Stunned, Abramovitz asked him the same thing — and forwarded the professor the fake offer email that Lee had sent.

“I’ve never seen that in my life,” Gilad told him.

“That’s when I knew something underhanded was afoot,” the student told the National Post.

He and a friend used one of Lee’s old passwords to log into the fake Gilad email account and saw that her email and phone number were listed.

“Miraculously, it logged right in. We felt like Sherlock Holmes,” he recalled.

Abramovitz, who now plays for the Toronto Symphony Orchestra, claims Lee pulled the same shenanigans by declining an offer he had received from the Juilliard School in New York.

The judge ordered her to pay $350,000 in Canadian dollars, or $260,000 in US dollars, for her “despicable interference in Mr. Abramovitz’s career.”

Lee didn’t appear for the hearing at which the judge issued the judgment against her, and couldn’t be reached by the National Post.

Abramovitz also sued for loss of reputation, but the judge declined to speculate what his career could’ve been had Lee not interfered.

But in an affidavit, Gilad made it clear that the special clarinetist’s career was hampered by her behavior.

“I am certain that had Eric not been robbed of his opportunity to study with me two years earlier, he could already have won an audition and been commanding this respectable salary two years earlier,” the professor said in the sworn statement. “I am very frustrated that a highly talented musician like Eric was the victim of such an unthinkable, immoral act that delayed his progress and advancement as an up-and-coming young musician and delayed his embarking on a most promising career.”
