A rep for the couple said yesterday their "busy schedules" had prompted them to part ways temporarily, but a source suggested to The Mirror there had been rowing behind the scenes.
Now, Stevi has broken his silence, telling the newspaper the couple are "very much in love" but just taking a breather for now.
Chloe is leaving next week for the Juice Master retreat in Portugal, a favourite among celebrities. Stevi said the time apart will "sort her head out" and help them get things together.
He told The Mirror: "We just have our ups and downs and Chloe has been feeling the pressure too. We've not split, we're just trying to sort our lives out."
The former X Factor star admitted having a long-distance relationship (between Bristol and Essex) was putting pressure on their romance, as was their desire to find a house and move in together.
It's all led to arguments and he confessed: "I have been a bit nasty with things I might have said at the time. We all do it. We're all human. [But] we still very much love each other. We're very much in love still."
He added: "I know we're still in love and we're meant to be."
They met on X Factor in 2014 and struck up a romance, which led to an engagement the following year. They appeared on Celebrity Big Brother in August 2015 as one contestant and finished in fifth place.
Speaking to Chloe in the CBB house in September, Stevi had said: "We were asked to do this as a couple and I had a lot of doubts. It's a big risk. It could either make or break your relationship but you know what for me I thought it would break us but it has made us a lot lot stronger.
"I just love you more and more each day. I wake up next to you, even the smell of our breaths don't matter, even without the make-up and all the glitz and glam of you. I just love waking up to you and I just can't wait until I get married to you and hopefully have a little bubba."
