I'm not saying women are better than men. I was mainly providing a counterpoint.
More importantly, when you make statements like "women can't bla bla", because of how the English language works, you automatically imply that men can do the opposite. So when you say stuff like "women can't love unconditionally", you automatically imply that men CAN love unconditionally.
I'm pretty sure we can all agree that things don't work exactly like that.
Realistically speaking, no one can truly love unconditionally. Plenty of mothers abandon their children for no good reason after all, and the same applies to fathers. Couples in general may do such things for any reason. Or worse things. Humans are not perfect, and unconditional love is beyond imperfect beings.
Basically, people can be scum, and that has nothing to do with gender, sex, or much of anything.
I disagree with the point you were making in the initial post. You were essentially implying that the issue came from the fact that the partner that cheated was a woman and the guy "couldn't understand how women work". In reality, it's just that she was scum, maybe, we don't really know the whole story there. (if it's even true, this IS the Internet, on a forum dedicated to hentai of all places...) Cheating rarely happens just because. Plenty of studies show that relationships in which cheating happens also have other issues that usually leads to it.
More importantly, I disagree with NTR having anything to do with reality beyond cheating being a horrible thing to do to someone when you're in a committed relationship... Cheating and break-ups happen for more complex reasons than "This dhick ish shooooo ghooooood." like how NTR generally works... and even a work like this one, which puts more effort into giving reasons for the break between Mary and Satoshi, still relies heavily on sex that pretty much doesn't exist in reality.
Using NTR as a lesson for anything about relationships and women is like using GTA as a guide for organized crime. Extremely stupid.
In any case, I'm not arguing that the world is sunshine and roses or the like. I'm also a believer in equality. (Everyone is scum equally, heh.) Which is why I dislike arguments that start with "women are" or "men are" in equal measure, and tend to have quick, knee jerk reactions to them.
Dunno what you think I'm thinking, but odds are, we might be on the same page on some things, we just disagree on root causes.
