'The trust was gone,' she said. 'I didn’t feel comfortable in my own home.'
WATCH: Mel threatens to leave Dino in an EXPLOSIVE fight
Going into the commitment ceremony on Sunday night, Dino apologised to Mel.
'I feel there’s something I did this week that was out of character,' he confessed. 'I recorded a conversation Mel was happening between her and her sister. It was a bad idea to start with and I’m sorry.'
Dino told the experts why he had decided to record Mel – because he was disappointed in what he was hearing her say about their relationship – which made Mel explode.
'I am so sick of you playing the victim,' she raged. 'Have you been recording me more times? I feel sick.'
John Aiken had apparently had enough by this stage, interrupting their argument to ask for final decisions on whether they were continuing in the experiment.
Both Mel and Dino revealed they had decided to leave, ending their time on the show – but not before Dino recited a poem he wrote just for Mel.
So much secondhand embarrassment!
