Is that, by chance, because it would means one does not trust one's lover and is possibly endangering various things. Such as one's self and as you say it hunaity as a whole?
Let's approach this by means of Socratic method.
Why it's stupid:
Would you consider cheating on your lover simply to see their reaction an act of premeditation, as opposed to infidelity due of impulse or intoxication?
Does such a premeditated act involve, by definition, intellect ("planning ahead") as opposed to instinct?
Would you therefore consider this premeditated act an implication as to the offending parties' intelligence?
Would you furthermore consider it oxymoronic to effectively destroy a relationship in order to measure its worth? Just like dropping an egg you intend to eat on the floor to see whether it is spoilt? Or like crushing your wrist-watch with a hammer to see whether it is running slowly?
Is it therefore not nonsensical to commit such an act?
Is it moreover not an expression of a lack of intelligence to knowingly engage in nonsensical, destructive acts?
Is it finally established that someone who would do such is lacking in intelligence, and can therefore without just reproach be referred to as STUPID?
Now that we've established that it's a sign of stupidity, let's move on to part two:
Why it's a danger to humanity:
I don't believe much in eugenics. But, I do believe that terrestrial resources are limited, and should not be thrown out the window lightly to promote idiocy. I furthermore believe that if this kind of industrial-grade stupid were to become any more wide-spread, it would endanger the gene-pool and lead to a devolution in the general direction of protozoa and archaea. A grim prospect, all said and done.
