"I forgave him, he said he was sorry. I won't forget, but I've forgiven him and we're still amicable."
Claire said she had tried to give the marriage a proper shot and if they had clicked she would've continued with the made-for-TV social experiment.
However she would not do this type of show again.
"[I wouldn't do it] just because you're out there in the public eye," she said.
"I mean, I knew that - I'm not stupid - but you just don't realise the emotional side of it. It's the emotional side of the show, where you're with this person 24/7."
Claire said she took the concept of marriage seriously (having previously being married for 24 years and having three children).
"I'm ready for a commitment so I can do the hard yards - I've done the hard yards.
"A lot of people think because I quit I can't do the hard yards - I can, Dom just wasn't the right person to do the hard yards with."
