The reason is because when a man treats his wife like a queen she treats him like a king. If he treats her like a slave, she will treat him like a shamata.
If a woman doesn’t treat her husband properly, he should check his own behavior towards her. Therein will usually lie the problem (sure, not always, but most of the time it’s true.)
However, if a man doesn’t treat his wife properly, usually has nothing to do with the wife’s behavior towards him (again, not always, but most of the time.) And sometimes it’s just tit for tat, but if he will change his behavior towards her, that will change too.
I’m sure I’m not the only one here who is able to figure out which male posters treat their wives well, and which ones do NOT.
