For every person who is truly "a control freak" there are often many more who aren't control freaks at all, but who exercise (or at least aim to exercise) more control over their own life than some other people believe they have a right to do. Since women, more than men, are often seen as "having a nerve" or "being a control freak" when they simply exercise control over themselves and their own life, I'm guessing that a lot of divorced women fall into the category as well.
The way I see it, if a woman is still married and is a control freak (a genuine one), the question doesn't apply to her. As far as divorced women go, a lot of women leave marriages in which husbands tried to be too controlling. So, you've got your divorced women who are "just right" when it comes to control, the ones who don't even bother trying to control anyone else, and those who are genuine control freaks.
I'm guessing that of any genuine control freaks who also happen to be divorced, at least some of them have become so sick of having other people messing up their lives, they may vow to never let anyone else mess up their days, lives, or anything else again. Whether or not such a woman is actually a genuine control freak, or just expects to control herself and her own life (more than someone else thinks she ought to) is where it can be difficult for some observers to see/recognize the difference.
