How authentic and objective can a guy's perception of his existence be (and the decisions he makes according to his understanding of what he sees and feels) when that "reality" struggles to pay a passing resemblance to objective truth? When people - in this case, women - let the mask slip and reveal their true selves for the first time, guys' first thoughts are almost exclusively, "Why did I not see this earlier?" He didn't see it earlier because he had no reason to. That suggests that "former life" of his was almost a dream of sorts. Yet he was happy to prolong that dream because either he was honestly unaware, or he'd wilfully deceived himself on some level.
This might sound comical, but I seriously mean it:
Any guys who don't have experience with women, get a female cat (a feisty one), let her be free to go outside: learn to understand and have a good relationship with her, it'll help with understanding your missus in future.
