Selin then gave Anthony a frosty reception after he walked in to the dinner party alone.
"I want to actually have that private chat with Selin because I'm not the kind of person whos going to have that conversation in an open platform in front of everybody," he told the cameras.
Domenica then made it clear she wouldn't shy away from grilling Anthony about his conflict with Selin.
"Anthony… honestly I don't even have words for this bloke. You've got a beautiful woman there and he left her on the honeymoon. I instantly clicked with Selin on the hen's so of course I'm going to have her back," she said.
Of course, it didn't take long for the elephant in the room to be addressed after the couples sat down for dinner.
When asked by Domenica if he regretted leaving the honeymoon, a visibly blindsided Anthony responded: "Does everybody know that?"
"Obviously Selin had told everybody her side of the story already. It threw me off guard I wasn't expecting that. I don't want to sit there and have a 'he said, she said' argument in front of everybody," he later admitted to producers.
"I don't feel it's my place to tell everybody my side of the story. The only person I need to have those discussions with is Selin herself."
But Domenica continued to push for answers on behalf of Selin, telling the father-of-one: "I just don't get why you would leave her" before Tamara implored Anthony to tell his version of events.
"It's a private conversation that I want to have with Selin," Anthony shot back, before Domenica cut him off, saying: "Which you could have had but you left."
"You say you wanted communication too but you left. I don't see that as being communicative. Why would a man that's come into the experiment to be part of this, why would you walk out?" Domenica continued.
Tamara added: "I feel like having that conversation prior to coming [to the dinner party] would have been a good idea. What did you expect?"
Jackson attempted to stick up for Anthony, but was met with backlash from Domenica who said he should have simply "gone for a walk" on his honeymoon to calm down rather than pack up and leave.
"Domenica and Tamara definitely had my back fully. They shut that whole table down. The girls are great," Selin said to the camera.
"I feel like I've put him under the bus but it felt really good venting. The girls had my back and how it played out was perfect."
MAFS experts John Aitken, Mel Schilling and Alessandra Rampolla expressed their shock over Selin's betrayal of Anthony.
"There's a lot of judgement coming at him from people he's never met. I'm sure that he's hurt... she dropped the grenades, stood back and let all the disciples do all the work for her," John remarked.
