Well, I remember my ex-girlfriend reading to me from a tabloid magazine about the reasons women offered up for cheating on their partners. One was that the guy they cheated with bought them a car. I asked her why she was doing this, and what she was really doing was projecting her own desires from the magazine.

In her own mind, she was living a relationship with her gym trainer. If I had been the owner of it, I would have said, "Right, the first rule is professional detachment. If A friend yours wants to join, that's fine, but under no circumstances are you to be their trainer. You must direct them to a colleague. And similarly, you are not to associate with your clients on a personal level.."

A cheater demonstrates that they are somebody who will always want more, and such a relationship is doomed from the start. A cheater will never find their soulmate because they cannot commit.

I remember somebody presenting a problem of a woman cheating on her partner, and two radio announcers had a discussion on it and asked people to ring in with their thoughts. I said that it depended upon the maturity of the people involved, but to remember that a cheater doesn't become a solo commitment person.

It's like drink drivers. My father was told not to hire them for the simple reason that, sometimes, it's an honest mistake and they only have one instance, other times, the person would come in and say that they were caught drink-driving over the weekend, and would lose their licence. So, the boss would say, "Okay, I can give you something that's not driving related until you get your licence back." They'd say okay. Then, a few months after they got their licence back, they'd come in and say, "I'm going to lose my licence, again." And they'd get fired.
