Thought of it, and would like to know whether anybody has any supporting or denying data. Also - how large is the issue? On the 1/3 range rather than the 1/10 is my guess.

It stands to reason that the sort of woman who'll cuckold a guy and get him to buck up, is also the sort who'll be more likely to divorce his sorry ass.

Whereas the women who'll stick by their men will have, on average, a better mental framework and thus also be less likely to cheat - and if they do, less likely to be dumb enough to get preggers off it.

What do you guys think / know?
