British actor Oliver Tobias and wife Arabella discuss parenthood; expecting second child

Oliver also has daughters Anjelika, 24, and Celeste, 20, with ex-wife Camilla Ravenshear but Camilla recently revealed that Celeste's father is actually Julian Metcalfe, co-founder of the Pret a Manger chain of sandwich shops but the news didn't make a difference,

It was an extraordinary event - and remains a very sensitive area for everyone involved. I still see both my daughters on a regular basis as there's nothing more important to me than my family.

After all you've been through, could you have believed that you'd now be sitting here expecting another child? Oliver: No. Not at all. But that's how life goes. It's quite unbelievable and we couldn't be happier. It's fantastic. I'm very proud of Arabella for having the courage to make the decision to have another. I have the greatest admiration for her. Do you feel you've turned a corner? Arabella: Certainly. There were times when I said to him: 'Please feel free to walk away. I won't hold it against you.' He said: "Forget it - I'm not going anywhere." O: They were difficult times, yes. That's when one has to just tough things out. Things do eventually turn the other way. Had you been planning to have a second child? A: Definitely. I didn't want Luke to be an only child. Have there been moments during this pregnancy when you've worried that the old problems might resurface? A: Of course, that's why it took so long for me to do it again. This time round I've got the skills to cope with things. During your dark days, what made you leave your husband and small son? A: I had no choice. I was admitted to hospital suffering a nervous breakdown. When I came out of hospital, we decided it would be best for me to live on my own and continue therapy. Thankfully, Oliver is the type of father who could cope. He and Luke adore each other, so I wasn't worried. So how did you cope, Oliver? O: It was hard work. It was a bit of a strange situation - a 58-year-old man and a two-year-old just muddling along together for five months. But we just got on with life. I even managed to potty train him. Did you feel suicidal, Arabella? A: Yes. But I knew I didn't want to leave my son without a mother and Ollie without a wife. What was it that brought about the reconciliation after five months? A: I got well. I was on good medication and had a wonderful therapist. And when you get yourself in to a better place and realise what's important, like being with your family, it all falls in to place. Do you feel you're now at the best place you've ever been? O: Yes, very much so. We're very, very, lucky.
