While Jess told her fellow participants and relationship experts she wanted to stay in the social experiment to introduce her TV spouse to her family, it seems her real motivation was to continue her adulterous flirtation with intruder groom Dan Webb.
WATCH: MAFS' participants react to Jessika’s surprise choice to stay
Jilted Mick opened up to 9Honey about Jessika’s betrayal, and admitted he had “no idea” his wife was planning to stay.
“We had a talk at the airport and she told me she was gonna write ‘leave’," Mick revealed.
“What a surprise – another lie,” he lamented.
Mick admitted he requested a separate room so he could "get away" from Jessika after she blindsided him with her shock decision, adding: "From the dinner party onward I tried to avoid her like the plague."
Meanwhile, Jess revealed her choice came down to encouragement from her cheating partner Dan who told her he wanted her to stay,
"At the time, I didn't even think about anyone's feelings - I just did what was right for me in the moment," she said candidly.
Jessika has since apologised to her on-screen spouse for her secret affair with Dan, acknowledging she has a "lot of regret".
