You may feel compelled to constrict women's dual mating strategy after reading my post, however, several studies prove that might be a useless endeavour:
When the adult sex ratio is male-biased, monogamous strategies are strongly favored. However, this is only the case if mate guarding is fully efficient, i.e., if there is no extra-pair copulation. On the other hand, in scenarios where the population is female-biased, or mate guarding is not efficient, we find that polygamous strategies are favored but proportionally to the dispersion of females.

The evidence showed no significant difference in extra-pair paternity (EPP) rates between countries despite key religious differences, they report.
EPP rates also rose with population density. Putting the two together, the researchers report that the estimated EPP rates for the families varied by more than one order of magnitude, from about 0.5% among the middle to high classes and farmers living in the most sparsely populated towns to almost 6% for the low socioeconomic classes living in the most densely populated cities.

Genetic traits were favoured for short-term relationships; material traits were favoured for long-term relationships. However, women with a more restricted sexuality preferred short-term mates who closely resembled their long-term preferences.

So, as population density increases and with female increase of survival (resulting women becoming the majority) due to technological advances, the likelihood of sexual monogamical practices declines, regardless of religious and (long term) mate guarding practices.
TL;DR: women want to and will cuck their SOs.
