When do you think a man should be ready for marriage and/or not living with parents anymore (22F)

Hello, genuine question There is a lot of controversy on when a guy specifically should be ready for marriage, and to be living alone or living with their partner. What age do you think is the cut off for a man to actually be independent both of those aspects? What will be the deal breaker if you were in your 20s dating how long would you wait for a man to marry you ? Also for those looking to date what age is it not acceptable for a man to still be living with his parents? Keeping in mind the age range stats at (20F) and (20M).

TL:DR: in your 20s how long would you date a man for before marriage and what would be your cut off time and for those who are single looking for a man what age is a turn off if they are still living with parents?
