The two, aged 35 and 49, were married for 11 years and share three children, but revealed they were separating in June earlier last year.
Speaking to OK! about the break-up, Christine admitted: "It’s certainly not a long-term or forever plan.
"It works right now because we’re both so busy and we’re in and out of the home so we tend to swap days and we’ll share.
"It’s much like any parent really – juggling jobs and children. We definitely don’t want to upset them or change anything too quickly, and for me as well.
"I like slow changes, and we’re alright – we’re family. I’ve known Paddy for 15 years, so I don’t know life without him. It is what it is."
She added: "He’s happy that I’ve found a place I’m comfortable in. He was very proud of my book and my documentary.
"He watched it and he loved it, and said he was really pleased that not only was I working but I was making a big difference as well.
"It’s good he’s supportive because I need him to be. I need to be able to leave happily knowing the children are being looked after and safe. It’s partnership and teamwork."
