Blackknight, recall that same book in that same article explained why monsters don't disregard men who are not heroes, that is any man they make their husband is going to become the best male for them. Ergo, even though monsters do consider heroes ideal men, they also know any man can become an incubus (functionally a hero as they are both humans who have broken their limits in one way or another), and so most of them prioritize other things when it comes to selecting a mate (things like how much the man wants them, how kind he is, even mysterious instincts that can tell a monster that he is "the one", and so on).

And monsters not leaving their loved ones is one of the hard coded rules of the setting. Not sure where you could have gotten the idea that it wasn't. To them, once they choose a mate, all other males cease to even be regarded as "male." Not that intellectually a monster doesn't know other men are men of course, its just that as far as her feelings and instincts are concerned her husband is the only male for her.

Now its not a guarantee that any one unmarried monster a man meets is going to jump them (there are various possible reasons a monster may not take a man as soon as she sees him), it's just quite likely. What is a guarantee is that he won't be excluded as a potential mate simply for how he looks or how powerful he is. What is also a guarantee is that if the man shows genuine interest and commitment even the few monsters that are more choosy will give him a chance.
