I have a number of non Jewish friends from school and they approach marriage differently. 2 friends who have been dating their boyfriends for over 4 years, live with them. One owns a condo together and the other rent an apartment. They plan I get married eventually but they are working on their careers first. For goyim it is not an unspoken rule that they pay for their kids weddings, and they do not support their married kids. It is very different for goyim. I have many frum friends who are 24, been maried for 3 years and have a few kids and are still 100% financially supported. I on the other hand am married with a child and we are not supported at all, although its not for me I do see the merit in waiting until you can support yourself
Lastly whoever posted about goyim getting divorced 3 or 4 times, sounds like someone is getting defensive because divorces are being much more common in the frum world. This year alone I know of atleast 4 girls my age who it divorced 1 from my very small high school graduating class. The problem isn’t only in the secular world.
