'Our relationship has really developed over the years. At first, I'd feel a bit lonely and inadequate. I had to learn to cook "kid" meals, and tried to make contact with other people who had little children, too. Funnily enough, one of my good friends was a single dad at the weekends and also had a son called Jack, so we would hang out together. But when Jack was really young, we could hardly go to a football match or rock concert, as we do now. Sometimes, if I was invited to a dinner party, I would take him along and settle him down in one of the bedrooms until going-home time, but he didn't really like that.'
