Jasmin, 25, and Ross attend Moses' birthday party at Altitude London – but they arrive separately, and she's hurt when he appears to ignore her all night.
Eventually Jasmin asks to speak to her man, and let's him know exactly how she's feeling.
She says: "We've just like, gone from one extreme to the next, one minute you're like, 'I want to marry you and stuff', and now you're like… you've just changed."
But Ross, despite being frustrated, insists that his feelings for Jasmin are the same. He responds: "I do [want to marry you] in every single way."
When former Ex on the Beach star Ross suggests giving each other some space, Jasmin ins't best pleased.
She replies: "You're basically saying that you've had enough of me and that you want to move out and stay with your friends.
"There's no point us being together if you're just going to let it be like this all the time, babe. I can't be bothered with it."
When a fed up Ross tells Jasmin to leave it, the argument escalates and she tells him: "Move out then, okay? Forget it, move out. I just don't see the point in our relationship. Right, I don't even know what to say."
