It was supposed to be a happy day to start the rest of their lives together, but Steven Weber sadly lost his life after proposing underwater to his girlfriend Kenesha Antoine
He emerged in the window of the underwater room where Antoine was at and showed the note to her
Giggling while filming her boyfriend's proposal, Antoine read the note which said, "I can't hold my breath long enough to tell you everything I love about you. But… everything I love about you, I love more every day!"
Weber then flipped the note to the back that popped the question "Will you please be my wife?" and pulled out the engagement ring.
Unfortunately, Weber failed to make it back to Antoine after the dive, as confirmed by her in a Facebook post
"You never emerged from those depths, so you never got to hear my answer, 'Yes! Yes! A million times, yes, I will marry you!!'," Antoine lamented on the post, which has gone viral globally with over 8,000 shares at the time of writing.
"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."
She described Weber as someone who was kind, compassionate, and brought so much joy to the people around him.
Antoine recollected how Weber told her that there were cancer patients vacationing at the resort and he felt blessed to be there at their prime, way ahead of their death.
"I know that wherever in the universe Steven's spirit now resides, that is exactly what he's doing: giving love and spreading joy and laughter.
"And knowing him, always quick with an off-colour joke, he's probably entertaining someone with a story about how he royally screwed up that proposal and died while being extra," Antoine wrote.
BBC reached out to the hotel who said "absolutely nothing could be done" by its staff when responding to the situation
Weber and Antoine were staying in the Manta Resort, off Pemba Island, where their room was submerged 10 metres deep and 250 metres away from the shore.
The room costs USD1,700 a night (about RM7,082).
"It is with the deepest regret that we inform that a fatal accident occurred at The Manta Resort on Thursday, 19 September 2019," the resort said in a statement.
Its chief executive officer Matthew Saus said "everyone is shaken to the core" by Weber's death.
Meanwhile, the US Department of State is aware that an American citizen has died in Tanzania, and the department is ready to provide consular assistance to Weber's family and friends.
