The drama began when 26-year-old Jess flirted with former rugby pro Dan in front of their respective spouses at a MAFS dinner party, with the meltdown queen going so far as to admit she was attracted to the new arrival.
And during Sunday night's commitment ceremony, Mick laid bare his feelings about his wife's betrayal declaring she is "always front and centre" when it comes to controversy.
Calling out Jess' flirtation in front of their co-stars and relationship experts, he asked: "Got something you want to say to Dan and Tamara? You were saying last night how attractive Dan is!"
Unphased, Jessika hit back: "Dan is a very attractive man."
Not afraid of showing his emotions, Mick asked his wife how she thinks her behaviour makes him feel and reminded her he hasn't looked at another woman since they tied the knot.
Speaking directly to the experts, the 31-year-old admitted their marriage had gone "downhill" and declared: "I'm just about at the finish line."
Defending herself, Jess claimed she was repeatedly blindsided by Mick who always tells her he's "fine darl'" when she questions him about his feelings.
Mick chose to leave the social experiment while Jess opted to stay, and her decision is sure to irritate her fellow brides who labelled the blonde bombshell "heartless" over her betrayal with Dan.
"Jess set her sights on Dan within minutes of meeting him,” says one furious bride. "She didn’t even hide the fact, telling the other girls she found him attractive, knowing full well Mick could hear her. He pulled her up about it because she was being so blatant and drooling over him at the dinner party."
Starting the shocking fling just hours later, the pair continued to meet in secret and lie to their respective spouses for weeks.
