She isn't talking about manipulation. Manipulation isn't a manifestation of love; it's a manifestation of a dwarfed, powerless egocentrism which will, in time, turn a woman's heart stone-cold if the calculated action doesn't achieve the desired result.
A confident, self-assured woman-in-love who truly wants to please her man will give everything she has to do so. A woman who doesn't love her husband and is going through the motions to get what she wants will find something of herself to withhold from him, and he'll eventually figure out that he's being played for a fool. Men can be quite slow, but by and large we're extremely sure.
Are you sure about that? ;) I guess it was just the way I read Dr. Laura's post.
