ujm:
That’s not true or relevant to this conversation. There is specific mention about boys marrying by 18, בן שמונה עשרה לחופה, and the Gemora says הגיע לעשרים ולא נשא אשה תיפח עצמותיו. There is no such statement about girls. If you have one, share the reference. If someone is not marriage material, regardless of any age, there is no posek that would push for marriage. I know that the “til death do us part” is a goyishe expression. But Torah does not push for marriage just to divorce or have a suffering situation because one or both parties are not ready.
Once again, Chazal are making a statement about expectations. Not a deadline.
