She continued: "I agreed with her comments when she said I was trash...I would be upset [about being cheated on] too."
However, in a twist, Jess claims Tamara actually gave her blessing to explore things with Dan, and insisted that her husband Mick also gave his blessing.
At the girls night, Tamara said, "You like my husband? If you like Dan, go for Dan". And Mick sat at the dinner table and said to Dan, "If you like Jess, have her".
However, she added: "It still doesn't give us any reason to do what we did."
Jessika went on to admit she felt guilty for keeping Mick around so she could pursue her secret fling with Dan.
"I feel terrible for doing that to that poor guy, I actually do genuinely feel terrible,: she said, adding that she and Dan should have simply left the experiment when they realised their feelings for each other.
"I know that I was hurting people, but this was my one chance to put myself first. I can't take it back, because it was worth it," she concluded.
Jessika and Dan are expected to reveal their affair during this Sunday's commitment ceremony, where they will plead with the experts let them continue the experiment as a new couple.
