I think that depends on your life experiences, and expectations of what a lifetime partnership entails. My hubby lived with his parents until he graduated college at 25, his mom's identity in life is MOMMY so she cooked and did things like take care of his laundry and pay his tuition past the point most parents probably would have. I left for college at 17, and had been cooking for myself and doing my own laundry from about age 12. When he graduated, we'd been together 3 years long distance, I'd had my own place, fulltime job and bills for two of those years. I was adamant that I didn't want to move in together or get engaged until he'd had some time to adult on his own- rent, first real job, cooking for himself, learning to iron(!) and all the rest of the things that his mom did him no favors by handling for him. I had no interest in invisibly picking up where she left off and being his new mommy- ain't nothing sexy about that. After two years in the same city but in separate apartments, he had some time to get a handle on things and mature a bit. It was the right thing for us to wait a bit. No regrets.

All of which is to say, if you're both aware of the daily grind and effort that it takes to handle the minutiae of life, do your part (and then some), are strong in life skills and willing to learn how to support each other, then you might be ready sooner than most. There's been a lot of research about how women tend to do an awful lot of unacknowledged labor- emotional as well as household- and men often let women be the project managers and "just follow orders," which leads to passivity and an imbalance that's often gendered. It's a generalization, of course, but if you're both committed to giving each other your best even when it's hard, that's a good start.
