We would meet in hotels, have sex – mindblowing sex - and then the realisation that what I was doing was irrevocably wrong would set in.
Taking my online affair offline was my big mistake, a transgression too far.
What drew me to the online world was the maintenance of fantasy.
And it was harmless, until I fell in too deep and wanted more than his messages.
And so our long-nurtured virtual affair became real.
Not all cyber sex addicts have these problems, but if they are present, treatment is essential to recovery.
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.
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.
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.
And I did, pretty much, and I was perfectly fine - until suddenly I wasn't.
There were redundancy problems at work; my marriage was showing strains; and there was something large and unnameable missing from my life.
We had agreed, early on in our relationship, that we wouldn't have children. Several friends, however, were convinced that our lack of children created a vacuum.
I was convinced I wouldn't make a very good mother and didn't want my son or daughter, in 40 years time, to dread calling me, fearful I'd berate them for some emotional crime or other. I'm not sure I entirely agree with that, but it is true that when we bought our first house together, we somehow conspired to buy a wreck that required a lot of our attention and focus. I didn't want an affair, nothing grubby, nothing seedy.
I ignored it until I could do so no longer, until eventually, for what felt like the sake of my sanity, I resolved to do something about it.
