Josie went on to explain that since she's based in NSW and he in Victoria, distance played a part in their break up.
"What we had was very real and we did give things a proper go for a few months after filming finished and it was working for a bit. However, a number of circumstances, especially distance began to make things extremely difficult for a long term relationship," she explained.
"Fortunately, nothing ended badly, things just naturally fizzled out. We’ve decided that the best place for us is a deep friendship and a platonic love which will never change and will be special to both of us forever.
"I don’t really want to or feel like I have to explain this too much, but I will just remind you all that a reality TV show environment can be a strange, weird and emotionally heightened place. George and I crossed paths at a time in our lives when we both needed each other and I will forever be grateful for that."
She added: "I can honestly say that George has really helped shape the person I am today. He has shown me what respect is, how to trust, the right way to be treated and how to learn to love myself again. George always has been and always will be an important, cherished and influential figure and role model in my life. He will always be special to me."
George, 27, shared his own post featuring photos of himself and Josie during their BATG experience.
"A while ago I was extremely lucky to have met this beautiful, intelligent and kind hearted woman. We went through some absolutely insane experiences together and I can’t deny that the chemistry and sparks we felt between each other was incredible and real," he penned in his caption.
"It has been a question a lot of people have wanted answered for some time so here it goes. Unfortunately Josie and I aren’t together. We really did try to make things work after the show and for a while it did. But long distance is incredibly difficult at the best of times, throw in the huge obstacles and complexities of a global pandemic and you have a far from ideal situation. We are both happy and in a great place as friends and I still feel such a fierce connection to you Josie."
The TV geek added: "Nothing will ever change the amazing things we went through or the lessons we learned together. You helped me put myself back together and really find myself again and I hope I showed you just how incredible of a person you are too. I owe you everything.
"I said it during the finale but whether you’re with me, with someone else or by yourself you deserve to be happy."
