And then it was finished: our nest, our empty nest. I became addicted to the attention and craved contact with the men I thought I had come to know. But I found out it wasn't as easy as I had first thought. I quit decisively at first, then slipped up, then quit again, craving some kind of patch.
My husband worked hard at his job and, to alleviate its accompanying pressures, developed his obsession with horseracing, gambling and drinking. These conversations quickly developed into cyber-sex, each message becoming more adventurous and racy and allowing me to live out fantasies I would never contemplate doing in the real world. My husband and I became strangers, our lives by now distinct entities. I told myself that what I was doing was essentially harmless.
It's taken me a good while to fully come to terms with what I've done, to understand how easily I fell into the previously unknown world that I would regrettably come to prefer to the real one.

He discovered messages on my phone and so I sat him down and poured the whole sorry tale out to him, feeling I was stamping on his heart with every word. I spent a lonely Christmas at my mother's house with nothing to do but wonder how I had got myself into this situation. I started therapy, and learned just how dysfunctional my life had been, and so little wonder I kept making new problems for myself.
I began writing everything down, to help make sense of it, first for myself, then for others.
And so our long-nurtured virtual affair became real.
He was young and beautiful and I couldn't believe that he wanted me.A late arrival into the world of social media, I nevertheless embraced it as a kind of escape.While my husband spent most evenings catching up on the horse racing he'd recorded over the weekend, I began perusing chatrooms – not in pursuit of cybersex necessarily, but initially more for harmless flirtation, a little virtual attention.I was a latecomer to counselling, having previously considered therapy a largely American pursuit. By the time I reached that landmark age, without children and in a marriage that was beginning to lose its fairytale glow, my daily life was beginning to feel not unlike a soap opera. And I did, pretty much, and I was perfectly fine - until suddenly I wasn't.Soon, I was spending hours in the parallel universe of cyberspace, often through wonderfully wide-awake nights, uninhibited in a way I never could be in reality.
