You don’t believe in doing this as a precursor to marriage?
It will fukk up your relationship. Most non married couples that live together never marry and split up.
Living with someone is not easy; it asks a lot of sacrifices.
When you get married, you accept to make sacrifices because there is a higher goal you're pursuing, which is founding a family. That's why you get married. Those things justify AND compensate the hardship of living with a woman.
When you're not married, you don't have that psychological barrier. You end up facing all the bad aspects of your girl without a reason to stay. People date for fun and pleasure. Living with the personn kills the fun.
Also, living with the girl without being married creates a limbo. It's like a marriage but it's not a marriage. There is no reason to fix a deadline for marriage. It's like a marriage without being one. People just waste their time till they get bored of each other
If you're ready to marry a woman, wait to be married to live with her. The fukkery of living with her for the first time is ,nothing compared to the general fukkery of marriage.
But if you' re ,not married, there is no reason to bother yourself with her presence 24/7. Living with a woman is a weigh and a limit to your peace that you should only accept if you decide to create a family.
