This story will give a warning sound to people in unconventional relationships that – contrary to what is always maintained, the so called open marriage or relationship does not always work, as one partner is bound to get jealous at some point.
Others simply harbour feelings of resentment towards their partner but chose to keep quiet in order to respect the agreed terms of the relationship.
But the silence does not always last and at some point, their true feelings regarding the situation are expressed.
This often leads to the break down in the relationship.
The Chase star Mark Labbett recently split from his wife after their open marriage failed to work, AOL has reported.
The 55-year-old TV quizzer and Katie, 28, have been married for seven years and have a three-year-old son together.
Labbett, known on the quiz show as The Beast, told The Sun On Sunday that “it’s got to the point now where I realise it is better for us to go our separate ways and remain friendly”.
He said the couple spent the past 18 months trying to make their unconventional marriage work after Katie told him about an affair.
“When Katie first came clean to me about her boyfriend, I’d had an inkling,” he said.
“But right from the start, my attitude was quite pragmatic – this was spilt milk, what could we do about the situation to make it OK?
“We had a family. We couldn’t just throw that away lightly. There were other considerations.
“But Covid provided the perfect storm. My mental health suffered and the differences in our ages became magnified.
“It’s got to the point where I realise it’s better for us to go our separate ways and remain friendly, without the stress factor of living together.”
Katie said: “I want everyone to know what’s what and that we are all happy. I just want Mark to be happy.”
The pair previously revealed that they discovered, after getting together, that they are second cousins, but “it wasn’t something we were aware of at the time”.
Labbett’s agent David Hahn said in a statement: “We can confirm Mark and Katie have split but will not be making any further comment. “
