"He had seen the video of me saying I was sexually attracted to Nic, and his ego was hurt," Jessika told News.com.au.
"He said, 'Obviously we’re not together now'," Jess said at Nova's MAFS dinner party.
"And I said, 'Whatever. I never got what I wanted out of this relationship anyway'. I was being a brat."
The pair reconciled just two days later.
Jessika, who has moved from Perth to the Gold Coast to be with her man and hopes to meet Dan's son soon.
"I moved three weeks ago. But as we say, his son's five [and] he's impressionable. We want to make sure that our love is strong enough to be there for him," she said.
"But he has seen a picture of me and said, 'Daddy, your girlfriend is pretty!'"
