The experienced climber who left his girlfriend to freeze to death at the top of Austria’s highest peak posted a harrowing message on social media just days after her body was recovered.

Thomas Plamberger, 36, paid tribute to his late girlfriend, Kerstin Gurtner, 33, in the since-deleted Instagram post — claiming her Jan. 19 death on the Grossglockner mountain “hurts so incredibly much,” Bild reported.

“I miss you so much. It hurts so incredibly much. Forever in my heart. Without you, time is meaningless,” he wrote.

He also reportedly co-signed the obituary penned by Gurtner’s parents in the wake of her death.

The revelations come after Plamberger was charged last week with grossly negligent manslaughter following a months-long investigation into the tragic ordeal.

Plamberger, an experienced mountaineer, is accused of abandoning his girlfriend roughly 160 feet from the summit when she started to struggle and could no longer continue on.

The couple effectively became stranded just before 9 p.m. — but Plumberger did not make an emergency call or give off any distress signals when they spotted a police helicopter fly nearby two hours later, local outlet Heute reported.

Plumberger called Alpine police officers at 1:35 a.m. and then set off about 30 minutes later in search of help.

At 2:30 a.m., he was spotted by a mountain trail cam descending from the peak.

His girlfriend, meanwhile, was left alone to battle -17°F temperatures and winds of up to 45 mph.

“The defendant left his girlfriend unprotected, exhausted, hypothermic, and disoriented about 50 meters [160 feet] below the summit cross of the Grossglockner,” prosecutors said.

When rescue crews eventually returned in the daylight, Gurtner had already frozen to death.

Plumberger’s lawyer has insisted Gurtner’s death was a “tragic, fateful accident.”

Prosecutors, though, have blamed the boyfriend — arguing he should have been more prepared for the trek.

“Since the defendant, unlike his girlfriend, was already very experienced with alpine high-altitude tours and had planned the tour, he was to be considered the responsible guide of the tour,” the prosecutors said.

“Despite the woman’s inexperience, as she had never undertaken an alpine high-altitude tour of this length, difficulty, and altitude, and despite the challenging winter conditions, the defendant undertook the alpine high-altitude tour to the Grossglockner via the Studlgrat with her in winter.”

Prosecutors allege the couple set off too late and didn’t have adequate equipment, given Gurtner was wearing snowboard boots and had no emergency bivouac gear.

Plumberger, who is slated to go on trial in February at the Innsbruck Regional Court, faces three years in prison if convicted.
