I'm not referring to the initial shit tests that women give you. Not those first ones. I'm talking about later, after the "honey moon" phase of the relationship is over. You know, that phase that we wish would just last forever. When its all new and she seems to just always be on her best behavior. When that ends, there will come some... new batch of tests. Without going into all the details on that, I'll just assume that whoever replies already knows what I'm referring to.

My question is this: What evolutionary purpose do those tests serve? Since we know that all these behaviors we're dealing with are largely evolutionary, then that one likely is too. But back in the hunter gatherer days, what purpose would it have served the woman to question, or otherwise irritate the man who had likely already impregnated her? Seems like a real bad idea, since at that point the situation very well could be that he has everything and she has nothing. He's got all the biological advantages and the skills, and she has to sit around and take care of a kid.

Seems a bad idea to test him more after this well known honeymoon phase is over. Maybe after she's been impregnated, he now decides she won't make a good mate (due to this new round of tests) and that it's best to just leave her to her fate. After all, we're talking about survival of the fittest here. Not modern times where survival is much easier.
