‘It Was a Difficult Breakup’: Married At First Sight’s Sean D Blames Painful Split With a ‘Crazy’ Ex for his Disappointed Reaction to Seeing ‘Bride’ Jo After he Muttered ‘Oh S**t’ at the Altar

He stunned Married At First Sight viewers on Tuesday, when he bluntly muttered ‘oh s**t’ upon seeing his ‘bride.’

And Sean D, 39, has blamed a bad breakup for his disappointed reaction to seeing single mum Jo, 39, walk down the aisle.

The Adelaide pub manager told The Fix on Wednesday that a former lover of 10 years left him so heartbroken two years ago that it still affects him today.

‘It was difficult breaking up, it wasn’t like either of us did anything wrong – there was no cheating or anything like that,’ he said.

‘She became a fitness freak but was just crazy. We slowly drifted apart and that was it, we were done’.

He added: ‘We had a five-acre property together, and she ran out of time for me and the animals. It was really hard because I had to take responsibility of the farm. I got all the animals. When we broke up, we had nine dogs, two alpacas, and two horses.’

As bubbly bride Jo was walked down the aisle by her young son, she instantly fell-head-over heels for Sean.

However, he could barely raise a smile after setting eyes on his soon-to-be wife.

After their wedding ceremony, vivacious Jo excitedly gushed in a piece-to-camera: ‘My expectations have been met, and then some. To infinity and beyond. Winning! Jackpot! I’ve won the lotto!’

She continued to giggle and gush: ‘The experts have been spot on! He is for me. He couldn’t be anymore perfect’

However, Sean was feeling far less elated about their marriage.

Speaking privately with producer, the nervous groom struggled to find the words to describe how he was feeling.
