Most women want to be in relationships/settled down by 30
it actually has a lot to do with their biology
their clock starts ticking as they get older
by securing a man and marriage/children by 30 or around 30 they will be able to live out their deep biological desires to have children
sure not all women want this but the majority do. it's an innate desire
The desire for children is mosly driven by peer pressure and society. If you would raise a woman in complete isolation, she wouldn’t even know she could get children. Our biology is still the same but our society has changed, which is why people get fewer children and at a later age than before.
