worder has it down to a tee, travelling men - also men who reach about 50 tend to go a bit mid-life crisisy and have to get 30 something girlfriends, start clubbing and riding motorbikes without a backwards glance to their wives or kids. think it's in your nature to be a cheater or not, to some people it is totally unacceptable behaviour to others they rationalise it. although i accept that people can change but if they've cheated in the past i'd be wary that they'll do it again, regardless of sex, as they have justified that cheating is acceptbale behaviour at least once before in their lives.
