Is this manipulation?

A follow-on from my previous question, http://www.fluther.com/disc/76690/how-do-i-deal-with-my-wifes-revelation-that-she-doesnt
After lengthy discussion, in which I explained how much difficulty I was having with regards my wife’s decision. She offered the following concession. She said that it’s not that she doesn’t want children. Just that she’d only want them under specific circumstances. These being that she could stop working until the children were old enough to start full-time schooling. Also, however, that she really wouldn’t want to have children much after the age of 35yrs (that’s just over 12mths away). As mentioned in the previous question, my wife is a Dr & is the main wage earner. She IS NOT prepared to accept a drop in living standards & there is no way, regardless of how hard I work, that I can make up the difference her being off work would create in our budget. I would literally have to quadruple my salary within a year to do this. I’m beginning to feel that I may have been manipulated in a big way by my wife & would appreciate your feedback. It seems to me that she has offered a concession, knowing full well that her terms are impossible to meet, & when combined with my previous question I’m feeling that I’ve been tricked into a marriage I don’t want.
