The reality TV duo met on the ITV2 show last summer and quickly made things official, before splitting earlier this month in the wake of their television show Crackin’ On.
Speaking at the TRIC Awards on Tuesday, Attwood told MailOnline: “Watching Crackin’ On was like when you go out and get drunk then watch your Snapchat story the next day and think ‘what have I done?’.
“It was like that - but for the last six months.
“There are some lovely memories there. It's hard but on the whole it's been nice. He watched the show with me.
“I had a girl’s night and he came round. It was always our plan to watch it together.
“Our relationship was always under pressure but [the show] was an added pressure. It's tough... I don't know [if it's over for us]. Watch this space.”
On Sunday, Hughes posted a touching - but strange - tribute to his 'co-parent' Attwood and shared a collage of them with their fake child, Cash, whom they nurtured as part of a Love Island task.
He captioned the Instagram photos: “Happy Mothers [sic] Day Olivia; keep smiling Doll, never let that tiara slip.”
But users soon commented on his “cringe” post, slamming their recent split as “fake”.
Stung, Hughes left a note on his own post defending his dedication to Attwood.
