Sponono breaks silence on Themba Khosa's betrayal

In the episode shared on the Engineer Your Life YouTube account, Sponono told the podcast’s host, Lungelo KM, how she discovered that Themba Khosa was on Married at First Sight Mzansi.

She told Lungelo KM that she discovered Themba Khosa had applied to appear on Season 2 of Married at First Sight Mzansi by mistake. Sponono said that after she discovered the betrayal, she confronted Themba, and he reassured her that she was only doing it to boost his career.

“I didn’t know. I only found out about the show later, I think, later December or early January. When I was using his laptop, that's when I saw the messages from ‘Married at First Sight’ saying you are going to the next stage and whatnot. And then you talk about it, he is like I am doing it for my career. I was not happy about that, but the person has decided and has gone through the stages without even consulting with me,” she said.

Sponono highlighted that, contrary to what some of the fans of the show might believe, she wrote to the show’s producers a week after Themba left their shared home to shoot episodes of Married at First Sight.

“And then for the first week and then the second week, that's when you started fighting. OK, I cannot answer your calls. I'm busy shooting. You know, it's not normal work, you must check up with me and make sure I'm OK. So that's when the fight. Because I wrote to the show a week into the shooting. Not now, after seeing the episodes. A week into the show. Now this guy is changing me? This is not what we agreed on,” Sponono explained.

Briefly News spoke to relationship expert Paula Quinsee shared why couples shouldn't ignore signs that a relationship is dying. She shared that if couples let the situation deteriorate without taking action, it can be difficult for them to fix things.

"If couples let this situation get too far, it can be difficult to bounce back from this even after repeated discussions or attempts at therapy, and the relationship erodes, impacting one’s personal identity, self-worth, and autonomy. When emotional exhaustion sets in, it impacts our ability to grow as individuals, as a couple, and the relationship may have more of a negative impact than a loving, nurturing one." Paula Quinsee explained.

“Themba abused her trust. Took full advantage and threw it in her face 💔”
