But she drove off and I was left standing in a deserted car park. I thought she hadn’t seen me. Instead, I had the police knocking at my door three days later. Lorna had complained that I was harassing her. They had a file. ‘Several instances of you approaching Lorna Kershaw.’ The policeman said he was there to warn me and asked me if I was planning on doing it again.

I told him that I was, if she carried on sleeping with my husband. I actually said that to them. Yes, I’ll keep following her. I’m not going to stop. That’s all they heard, not the bit about her sleeping with you. Their silent shock shook me into reality and I realised that I was in trouble. They took me down to the police station and cautioned me.

You arrived to bail me out. I wasn’t charged because you persuaded Lorna to drop the charges. You got me a solicitor and I asked to read the file, which was when I found out exactly what your tactics were.

Caroline is a little bit disturbed. She’s imagining that I am having affairs with women I work with and with friends. Lorna has agreed to drop the charges on the condition that Caroline gets help.

Even then I convinced myself that there had been some massive mistake. That you were just doing it to get me off. That we were still in it together. You were on my side. But soon afterwards I found myself sitting in a counsellor’s office. Of course, I knew her techniques. People-centred counselling. Everything out in the open. It was my chance to finally make someone understand what you’d been doing.

I told her all about Christine and Lorna and Julie and what I had seen. She had the case notes from my solicitor and her recommendation was that Jack and I had considerable difficulties and that we should go to marriage guidance in order to resolve them.

Obviously, I didn’t think you were going to immediately admit that you were having an affair. Or affairs. But I did think that you loved me. That we were a family. That you would protect me. That you knew what you had done and you would at least keep quiet and just not deny it outright. Do the decent thing.

But you have to be right. And you know me; I’m going to defend myself to the death. So we were at loggerheads and you had the advantage. The marriage guidance was a disaster. Mrs Simister, a tiny, middle-aged woman, sat between us. I accused you of having an affair and you denied it. Not one single new situation came out of it. I got more and more upset and annoyed as you insisted that I was imagining everything.
