You just have to recreate conditions of their evolutionary past. This is what their instincts are honed for and expecting.
You already have a built-in guide:
Your alphaness.
Women were subjugated by men for their entire existence until the 1960s. Evolution hasn't had time to change the script yet. It's so fvcking ingrained and impressed upon their brains that they will run the script if you don’t. They will treat you as disposable, use you, dominate you, make you insecure and leave you wondering if she is committed to you or not.
Having women hasn't prevented me from falling in love.
But a lifetime of options has prevented me from sacrificing what it takes to remain in love.
I also do not believe that men can understand women completely since the feminine is not a logical concept. It's irrational and ever-changing, the people who do get it, don't get it because they understand women, they get it because the accept the feminine and don't get frustrated when things are illogical. Of course you can understand a few aspects of the feminine like; seeking attention, desiring to maintain social relationships, changing their mind rapidly, etc, but as a whole, the feminine just can't not be understood. It can only be accepted. And when you do accept it, you get to choose how it will effect you.
The mind is a reflex organ, with millions and millions of synapses and connections determined by all sorts of stimulus. You can have the most perfect women in front of you, someone who gets all the checks on all your boxes, but there is no guarantee, as perfect as she is, that her love toward you will remain the same tomorrow nor your love toward her. And that's just a fact of life. So we engrave all the best memories that we can and embrace the uncertainty.
