The Irish model was evicted from the Celebrity Big Brother house on Friday night, after being involved in this series' most talked about and controversial storyline.
He admitted to falling in love with former Hollyoaks actress Stephanie, despite her being in a relationship with model Sam Reece for the past year.
Speaking to The Daily Star Sunday, Jeremy said: "I know that she wouldn't sacrifice a relationship that she thought was solid or she wanted to marry this guy. Steph told me things that she wasn't happy about. Obviously there were chinks in the chain in Steph's relationship. She wasn't happy. She obviously thought she found something better."
Jeremy, 25, added that he now wants to shower Stephanie, 22, with attention and make her realise what an amazing person she is.
"I knew I would be able to treat her like a woman," he said. "I want to show her how important and talented she is. She doesn't know how cool she is."
Stephanie has made no secret of the fact she really misses Jeremy, hugging him and crying when he was evicted on Friday. He had faced the public vote against her and Tiffany Pollard.
On last night's show, she said: "I came on Celebrity Big Brother and met a guy from Ireland and he was everything I wished for and more, and I ended up kissing him. But in my defence, I've always been a loyal dog and have never cheated on anyone before.
"I met a great guy and I'm so excited to see him. I love you Jez."
