Jess was prompted to speak out to the online publication after rumours started last week that the ill-matched pair had got back together when Seyat shared a picture of himself with a brunette that could have been mistaken for Jess.
"That's not me - it's his girlfriend, the one he cheated on me with right after the show ended!" Jess revealed.
"I haven't seen or spoken to Seyat in months and I really don't plan on it.”
The student then proceeded to reveal exactly what happened in the lead-up to the couple’s split.
'He didn't want to support me studying in Townsville,' she explained. 'He wanted me to stay living at his house with his mum [in Melbourne] and wasn't willing to grow up and be mature the way I was.'
'Two weeks after the show he decided to cheat on me with his ex and left me, then he wanted me back after he'd had his fun.
'But it was over for me by that time. I don't want a cheater. He was going out and leaving me at home and all I would get were messages about him being all over other girls and I didn't deserve that.'
Jess famously suffered horrendous verbal abuse from Seyet’s mother during her time on the show, with Fatima saying the reality star 'dresses like a prostitute', was a 'slu**y party girl', 'w***e' and 'smells like cats'.
Thankfully, Jess hasn’t let the split get her down and has been throwing herself into her studies.
'I've been focused on bettering myself,' she said. 'I've got an amazing job, I'm living out of home, and studying something I love.
'I'm working and studying extremely hard and all he seems to be doing is the same old clubbing and running back to his ex-girlfriend.'
She added: 'We're on bad terms because he has said horrible things about me on social media and he cheated. I have no interest in speaking to him.'
While Seyat has yet to comment on the relationship breakdown, Jess has indicated that she will be seeking a divorce – the couple wed at the end of the show last year – once they have been legally separated for 12 months.
