This sort of ties in with what I wrote here: http://www.theyeshivaworld.com/coffeeroom/topic/why-are-some-people-so-smart/page/3#post-533544
Women are taught that there whole purpose in life is to get married, have kids, and help their husbands and kids succeed in Torah and religion. I such a system, they will feel bad if they are not married because they are made to feel as if their current existence serves no purpose. Similar to what writersoul is saying I think.
