the best way to achieve this is to leave this idea to the fairy tale you got it from. look, I get it and I am in the same boat with you, I'd prefer this type of arrangement. as many of the other guys on here are pointing out, there are many, many, many reasons that this is an extremely unlikely situation for you to run into. you'd be better off going out and panning for gold, hoping to strike it rich. you'd be better off sinking all of your next few paychecks into the lotto in hopes of winning the jackpot. betting on modern day women in today's landmine of a legal society we live in, that's a fool's errand.
take it from a guy who thought, oh, I couldn't possibly get into a second bad marriage, I know better now. no respect, no sex, no control over my life generally, that's what awaits the vast majority of men once they get into marriage, me included. we make that mistake because we want that type of partnership in life but that's not what the vast majority of women offer. they offer the high of the initial relationship, the high of vast amounts of sex. it's like taking someone out to the bar, getting them drunk, promising them the world and then leading them into a bad business deal where no matter how crappy of a business partner they are, they get half of the assets and half of the money when they bail out of the business. a lot of us, we'd unfortunately be much more likely to enter into that arrangement when we're drunk, same thing that most women do when the ply you with sex early on in the relationship, it's to get you too drunk to think straight when they hit you with the sh*tty business deal.
