Casey, 31, revealed she couldn’t keep up with Dreamboy Rogan’s lifestyle – preferring nights in over wild parties.
Speaking to the Daily Star Online, the former Celebrity Big Brother star said: “Yes I’m single, it was a whirlwind romance and was fun but Rogan is just not the right guy for me.
“He is a lot younger than me and we are completely different stages in our lives.”
Casey added: “He goes out to a lot of parties and I am a bit older. I’m past the party life now, I’ve done it all. I’m a stay at home, get up and ho to work girl rather than staying out all night and going to work hungover – I’m too old for that now.”
Casey and Rogan were first pictured getting cosy at the launch of The Dreamboys 2016 calendar last month.
At the time, stunning Casey admitted she wanted to ‘tame’ Ex on the Beach star Rogan.
She said: “There is a reputation there but I feel like he may have met someone now that makes him want to top stop his reputation.
“I may be the one to settle him down, I’d like to think I could be.”
Earlier this year Casey insisted that she was abstaining from sex until she found Mr Right.
