A dream vacation turned into the stuff of nightmares when a man died while proposing to his girlfriend underwater, according to a report.

Steven Weber Jr. and Kenesha Antoine were vacationing in Tanzania and staying in an overwater bungalow with a bedroom submerged in the sea when Weber Jr. popped the question early Friday, the Louisiana Advocate reported.

A video Antoine posted to Facebook shows him swimming up to the bedroom window with a plastic-wrapped note and a ring box.

“I can’t hold my breath long enough to tell you everything I love about you,” the note read. “BUT . . . everything I love about you I love more EVERY DAY!

“Will you please be my WIFE? Marry me??”

Antoine can be heard laughing with excitement in the background.

Wearing a snorkeling mask and fins, Weber Jr. is seen swimming back up to the surface, but he never made it to the top, Antoine said.

“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 wrote in the heart-wrenching social media post. “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.”

The post shows the couple in happier moments on their trip: during a safari with a giraffe in the backdrop and giving their Facebook friends a tour of their tropical abode.

It’s unclear how Weber Jr., a residential assistant at an addiction rehab center in Baton Rouge, Louisiana, died.

The US State Department said it is aware an American tourist died in Tanzania, WBRZ in Louisiana reported.
