"I lost the love of my life." Boyfriend of Annabelle Falkholt shares emotional tribute.

The boyfriend of Annabelle Falkholt, who died from injuries sustained in a car crash on Boxing Day, has shared an emotional message saying he has lost the “love of my life”.

Lars, 69, Vivian, 60, Annabelle, 21, and Jessica, 28, spent Christmas Day with their extended family on the New South Wales south coast.

But the following day the family-of-four would be torn apart after a head-on collision at Mondayong, that killed Vivian, Lars, and the driver of the other vehicle, Craig Anthony Whitall, instantly. Annabelle and Jessica, who were sitting in the back seat, were pulled from the wreckage.

Annabelle, a child care worker, was taken to Liverpool Hospital in a coma, where she died on Friday afternoon.

Jordan Brohier wrote, “the 3 years I knew her were the best years of my life. I’m so thankful for every second I got to spend with my baby”.

"I just keep hoping that I'll wake up from this terrible nightmare and see her gorgeous eyes looking back at me.

"She was the most amazing girl I've ever met, loved by everyone that came in contact with her. Even though I would loved to have spent the rest of my life with her, I am happy that she is pain free and smiling down on all those who were lucky enough to have her in their lives."

Brohier described the last few days as "the most painful thing I've ever been through".

"You were the best thing that ever happened to me".

He ended by reminding others to be careful on the roads, where a car is a "deadly weapon".

After the crash, a cousin of Jessica and Annabelle thanked Darien Collier, the Wollongong man who pulled the women from the wreckage.

"Words can not express how grateful we are," she wrote.

Collier wrote that to describe the crash as horrific would be a "massive understatement," and said, "the injuries on the two girls will be something I won't forget in a long time".

Our thoughts are with all those affected by this tragedy.
