Nonchalance imo is just a spice to add in if you add to much they just think you are an asshole and not in a charming good way.
I prefer the term carefree, You don’t care at all if she goes home with you likes you or whatever, And you are fully relaxed, Seriously relaxation is the single most crucial thing.
But you are still curious about getting to know her
I was on a date all I did was get to know her without really escalating physically, Just letting the date unfold as it wants too, A few hours go we are having fun but not any super big iois from girls. Except the most important one she does not want to leave,
Then she ask so can I come home with you?
Also be sure wanted is your style of seduction, Read through the wanted and primal seduction copy and really think about what resonate with you the most,
I got way more results with primal seduction, since it matches my being more, I even got approached more, which was a bit of a confusing thing.
Even though I liked the copy of wanted black more it looked more grand and cool, it did not match me
Best of luck on your journey.
