The words Morality, decency, respect, consideration for others (particularly any children whose lives get stuffed when families break up), spring to mind.
All these sordid, underhand 'affairs' are just that, sordid mean and underhand when you don't exercise Morality, decency etc.
I had some very young glamour puss (I'm a Dad not a Mum) just openly proposition me simply saying that I wanted an extra bonk anytime, she fancied me and was instantly available.
What a turnoff I have to say !
She knew I was married. I was a lot older, I had probably never even spoken to her before and was almost unaware she existed.
What a Pratess.
A good example of a vile and disgusting person of the sort that often breaks up families.
Unfortunately, My wife met a male version who had already managed to wreck several families.
And the only things wrong with my wife's marriage to me was the state of her obviously damaged brain.
By which I mean that it became clear only after I married her, that her various parents - real mum, adoptive mum & adoptive dad, then stepmum and completely unknown real dad, had all combined to provide a number of real traumas and upbringing absolutely guaranteed to make any child into an adult psychopath - which is pretty much what my wife became.
Maybe if I had dallied with the glamour pess I might have had a better deal after all, as my wife has certain completely wr4eckedc my whole life from the age of 28 to now at 61.
i.e., as direct result of her actions and behaviour I am spectacularly finacially and career wrecked and wrecked in terms of all normal relationships and social life which people have.
this is because a series of events has left me the single dad of an eleven year old child and all my normal social and family contacts have been smashed to bits by first my ex-wife, and secondly a schizophrenic woman I would never have met if my wife hadn't left me single again.
You may say it is not my wife's direct fault I compounded her buggeration up by allowing a schizophrenic into my life, and that is true.
But all life is due to random chance events and the schizophrenic was one of those unpredictable things that I was protected from by being already married and thinking I would never been available unless my wife died.
As she waas eleven years younger than me it was unlikely I would ever be in the market again as I was total loyal etc. You know that for better or worse and in sickness and in health thing.
I really believed in that and it's a pity so few people do.
