MAFS UK's Polly to storm out on groom following shock revelation about their marriage

Married at First Sight UK fans are bracing themselves for another fiery episode as a heated argument breaks out between Polly and husband Adam, resulting in her storming out on him.

In last night's episode (October 30), the couples were given the task of penning anonymous letters to their fellow participants, offering advice on how each relationship could be improved. This followed the partner swap week, where the brides and grooms were mixed up to see how other partners treated their spouses.

Adam was paired with Amy during the swap, who claimed he treated her like a "princess", while Polly was matched with Nathan. During the switch, Adam shared a bed with Amy and even accompanied her on a lingerie shopping trip, which stirred up Polly's insecurities about their own relationship and its lack of intimacy.

However, in the anonymous letter given to Polly and Adam, it was suggested that Adam's feelings were being overshadowed by Polly's, reducing the bride to tears as she questioned her behaviour towards her groom. The letter arrived shortly after Adam had confided in Polly that he didn't feel his needs were being met, as she continued to pressure him for more public displays of affection and intimacy.

Despite Polly's moment of introspection after reading her letter, the tension between the couple is set to escalate in scenes that will be broadcast on Thursday night (October 31), reports .

The new episode of Married At First Sight UK promises drama as the couples start living in each other's homes. One noteworthy moment features Polly cooking while her partner remarks, "I hope you're not going to make too much mess," which clearly doesn't sit well with her, judging by her reaction.

Tensions seem set to flare between them once again as Polly struggles to keep her composure when Adam's friend quizzes her about the marriage, and she admits that it's "hard."

A subsequent dispute sees Adam accusing Polly of making him look "muggy as f***," which prompts her to jump up from the sofa and tell him that "you actually take the p***."

The quarrel intensifies as Adam throws out a major revelation about their marriage. "You're lucky I carried on this marriage after you did that. Simple as that," he says, causing Polly to hit back with, "What is actually wrong with you?".

Reaching boiling point, Polly confides to the cameras, "I feel like I've really reached my f****** limit," before walking out of the house and slamming the door behind her.
