From the book- Bringing Your Fiancee Home by William Livingston. . . .
"She agreed with me that children were not important to her and that she would abide with my wishes not to have any children in our marriage. Then she dumped me for another guy.” Biology takes over- a fertile woman with no children is not going to agree to a sterile relationship. This is the basic human urge to reproduce.
Sooner or later, natural urges will come into play. Come on, get a clue!! She is going to have that baby somehow. She will agree with you at first, hoping to persuade you later that you should have a child with her. If she does not have that baby with you, then she will have one with her next husband after she fails to talk you into it. You need to set yourself up for success, not for failure.
So, for you fifty-something guys out there seeking to marry a college kid without children, rest assured, there is a baby in the future. Maybe not in your future, but definitely in hers. So- you would be better off spending your time looking for a thirty-something lady, preferably with a child, and set yourself up for a successful, lasting relationship.....
It is not cultural- a natural state is reproduction of species. If she doesnt have one, 95 % will want one. You are better served in revising your criteria-both in age and in existing children
