I was lying next to my poorly son in hospital when he phoned and told me what had been going on. I don't know how I got through the next few hours. As I cradled my baby, all I could think about was Jock and Nikki together. My world fell apart that day. I can't believe they managed to keep it hidden all that time. It really was the ultimate betrayal.

He was totally alien to the man I knew and loved. It was like he had a big black cloud hanging over his head. But even then I didn't suspect he was having an affair.
