During a Tuesday appearance on Married at First Sight: Unfiltered, which is hosted by Jamie Otis, Dr. Jessica suggested she and the show's other two experts -- Dr. Pepper Schwartz and Pastor Calvin Roberson -- regret ever matching Luke and Kate to wed in the first place.
"So many of us have times in our lives where we make a decision and wish we could have done it differently," Dr. Jessica explained.
"And both Kate and Luke were vivacious people and there were so many reasons why we thought they would be such a good match."
But Luke and Kate's marriage has been "a downward spiral," as Jamie put it on Unfiltered, and the majority of Married at First Sight viewers have blamed Luke for their issues.
Luke was not attracted to his wife at first sight, admitting she's not his type, and he never appeared to try to build physical intimacy.
And as the season progressed, Luke confessed to his wife he felt "repulsed" and "dead inside" when sharing their first real kiss after the wedding. He also later accused Kate of having a drinking problem.
In turn, Kate has been confused about how to fix things, and in previous episodes ofMarried at First Sight: Unfiltered, she vented about Luke's bad behavior was a slap in the face and made her lose trust in him.
"What's been hard to watch is how volatile their relationship is with the ups and the downs and that it seems they are hurting each other more than they are actually helping one another or are caring about one another," Dr. Jessica explained.
