Married At First Sight UK's Kieran Chapman has vowed to take a social media break after receiving a wave of backlash from viewers.The Newcastle-based mechanic, 28, who was matched with dog walker Kristina Goodsell, 31, from East Sussex, initially seemed like the couple to watch on the show. However, recent episodes have seen Kieran get cold feet as he compares Kristina to his ex. A particularly tense moment unfolded on Tuesday's episode where a 'petrified' Kieran shared a list he made that compared Kristina with his ex much to the dismay of his on-screen partner.
