Any man that is willing to sneak around with her behind YOUR back and have sex with her... and ruin YOUR MARRIAGE while he gets off like some sleazy stalker... is NOT going to lead your wife down any safe path in the long run
less than ONE PERCENT of affair couples survive long term.. most end up breaking up in an ugly fight or one of them again ends up cheating on the toher... the success rate for affair couples is VERY LOW
From THAT YOU can imagine that any guy your wife runs off with is NOT thinking in HER best interests and will NOT put her SAFETY as his first concern...
Any guy that mounts someone else's wife is NOT putting that woman's safety as his first concern...
THAT is my concern, that your wife will hook up with a creep and get physically and emotionally hurt
Never mind morality and forgive me for saying so but never mind you.. affairs are physically DANGEROUS
