“Most men know exactly what it would take to make their woman happy. They’re just too stubborn, too egotistical or too lazy to do it.”
I believe most women, who have been with their man for any reasonable amount of time, want their man to know exactly what it would take to keep them happy. You drop subtle hints, you outright say it, and when you don’t, it still comes across through your actions and reactions. So, for the most part, he should know. If he knows and still doesn’t do it, it’s most likely because of one of the previously mentioned reasons. If after all this time he still doesn’t know, he simply hasn’t been paying any attention to you at all.
