Hashem created the woman primarily to be her man’s *eizer knegedo.*
To say that she was made to bear children and raise them is complementary towards being an eizer; yet not her raison d’etre. Only Hashem is in charge of who gives birth. Raising children is one tafkid, but it’s not the most vital, ironically.
If it was to stay at home raising children, then the Lubavitcher Rebbe’s Rebbetzin would have missed out on her calling. Yet she did not. Her purpose was to support and lift up her husband, according to his needs. Furthermore, there are couples that marry later. Even then, the wife is the eizer knegedo.
How that plays out depends on the individual couple. Generally it’s about the woman’s special intuition, where the husband gains insight through his wife. The wife offers the husband something spiritual and beyond tangible, foremost.
