Heartbreaking simulation shows what 'went wrong' as man tragically died trying to propose to girlfriend underwater

A YouTube simulation has revealed what happened when a man tried to propose to his girlfriend underwater but drowned.

Steven Weber and his girlfriend, Kenesha Antoine, were on holiday in Tanzania in 2019 and the trip was once-in-a-lifetime, not just because the pair were staying at a luxurious resort, but also because Steven was planning on popping the question to Kenesha.

The couple were staying at the Manta Resort of Pemba Island when Steven got his goggles on, armed with both a sealed sheet of paper and a ring and dove into the water to swim up alongside the glass wall of the pair's cabin to ask Kenesha to marry him.

Steven pressed the page up to the glass window while she was filming him, with the paper reading: "I can't hold my breath for long enough to tell you everything I love about you BUT everything I love about you I love more EVERY DAY!"

He then flipped the paper over, it asking Kenesha for her hand in marriage and then he brought out a ring.

However, Steven never returned to the surface and a simulation has since been shared as to what may've happened.

Zack D Films shared the simulation creation to YouTube, as the clip explains as Steven 'tried to swim back up for air something went terribly wrong'.

"He never made it back to the surface," the video continues.

The post adds the resort confirmed that Steven was 'freediving' during the proposal and 'drowned'.

At the time, CEO of the resort, Matthew Saus, told the BBC that staff responded to a 'problem in the water' during Steven's dive, but when they arrived 'absolutely nothing could be done'.

Indeed, freediving blog Padi explains some of the risks of freediving, noting it carries 'some inherent risk due to the nature of the activity. Going to depth puts pressure on your body'.

The website states: "The most common depth or pressure-related risk in freediving is barotrauma injury (injury caused by pressure change) to the eyes, ears, sinuses, and lungs. These are almost always caused by a failure to equalize correctly or by moving too quickly on ascent or descent. "

Other warnings include not freedizing along, making sure you're 'well hydrated' before and being careful of not forcing how far down you go in the water.

Shortly after the tragedy, Kenesha took to Facebook to pay tribute to her partner.

In a post shared on September 20, 2019, she wrote: "There are no words adequate enough to honor the beautiful soul that is Steven Weber, Jr. You were a bright light to everyone you encountered. You never met a stranger, and you brought so much joy to so many people. You were kind, compassionate, you regularly made me cry with laughter, and you showered me with a love like none I’d ever experienced.

"You never emerged from those depths, so you never got to hear my answer, 'Yes! Yes! A million times, yes, I will marry you!!' We never got to embrace and celebrate the beginning of the rest of our lives together, as the best day of our lives turned into the worst, in the cruelest twist of fate imaginable."

Kenesha added she had been able to 'take solace' in the fact they'd just enjoyed a bucket list holiday in the days running up to Steven's death, describing them as 'so happy and absolutely giddy with excitement in our final moments together'.
