Married At First Sight Australia has already aired a whole range of unexpected and dramatic moments, including Jesse and Claire's solo entry to the series' first dinner party and Melinda's snub at her new hubby - but on tonight's episode (which aired on Wednesday, March 15), one couple's love story took an even more shocking turn.
Not only did Shannon show little regard for his new wife's emotions when he ranked two of the other female participants as more attractive than her, he also broke her heart on camera when he admitted that was still in love with his ex.
Shannon had previously explained to the programme's love experts that his most recent relationship was an on-off relationship with his daughter's mum, which spanned seven years. He told Caitlin that this relationship with his ex had been "toxic" but that he often couldn't help himself but go back to his partner, time and time again.
