While having lunch with Lydia Bright, Georgia Kousoulou and Tommy Mallet, Kate confides in them about her relationship with Dan, revealing that he is no longer prioritising her.
The conversation leaves Kate teary-eyed, and after Lydia gives her some words of wisdom, Kate later has it out with Dan at the pub.
But it looks like more tears are in store. Will they be able to sort out their issues?
During Sunday's episode, Kate accused Dan of spending more times with his friends than he does with her.
The short but heated conversation left Kate a little tearful as she told him: "You see the boys nearly every single day. We see each other in big groups but we don't see each other on our own, me and you, and the one night that we do you go and leave to see the boys again."
