Then especcially what the point of it? Either give player choice to make his own desicion, like if player want to keep the mystery of whats going on, then he won't choose wife's POV (OK maybe many won't follow it, but still). But if he decides to choose it than show all her POV.
Or if it is intended to be a mystery, no wife POV, but as example, some talk recordings or vids that husbund finds or someone sents him, or something else, that is not clear but may hint on something.
Cause this stupid move with partial POV of wife is already done so many times that it is IMHO - first boring, second - once again stupid. As if main character is husband and game is played from his POV, wife's POV kinda doesn't make any sence within the story, cause husband won't know it and it won't left him questioning, but player. But wait it is a porn game so hmm... The other thing is if we follow/choose husbands actions not knowing where it may lead him/us, this type of mystery is more interesting, well at least for me.
