To justify her actions, Debbi said: “Well, when you’ve got a good man, you’re not going to let him go, are you?” The following year, the pair returned to the show, and Steve claimed they had slowed down on the testing and said they use the tests “as many times in a month as [they] would in a week” and sometimes “even less than that” and added it’s “more like once in a blue moon”.

The pair also revealed that Steve has restrictions on what he can watch on TV too, to keep his wife’s jealousy at bay and reassure her he wasn’t “eyeing up women” on TV – so he isn’t allowed to watch any shows with women in. Debbi told The Mail: “One night, an advert for a women’s razor came on television and I felt panicky thinking that Steve was eyeing the model up. The only thing that could put my mind at rest was banning him from watching any programmes that have women in them.”

She further explained she can “understand a man admiring somebody that’s beautiful because all women have an inner beauty and an outer beauty” however her issue is when men start “sexually fantasising” about other women – something she doesn’t want Steve to do.

Debbi explained that she had a “previous traumatic relationship” that has led to her jealousy issues, as well as being diagnosed with a “recognised medical condition” called Othello Syndrome. According to the National Library of Medicine, it’s a condition that is a “psychotic disorder characterised by the delusion of infidelity or jealousy; it often occurs in the context of medical, psychiatric or neurological disorders.”

Although Steve is restricted to doing certain things in their marriage, which can take a toll on the pair, he said: “When we’re not arguing about this, our relationship is absolutely amazing. I make her laugh in ways she’s never laughed before. She makes me laugh in ways I’ve never laughed before.”
