What do you think "Living on your own and learning what it takes to run a household." Means? It incorporates cleaning, paying the bills, home maintenance items, etc.
And I promise you, I have done everything on this list - because becoming a whole, self-sufficient individual means growth in all aspects of life. There's nothing "1950's" about learning to take care of business.
And learning to take care of business increases your confidence. I guarantee you I attract a whole lot more men now that I've got my shit together than I ever did when I was young and dependent. This is simple human nature/attraction.
My sons are both ambitious and aren't willing to date a woman who will simply be a drain on their resources, if you are that's your own issue.
Being caring, soft, and go with the flow has literally nothing to do with getting your shit together and knowing your worth.
You want a healthy partnership? Get your shit together.
