it's actually true.
Once you get to a point a woman feels like you got her 100% and she doesn't have to worry about anything being with you, she'll be down for you 100%.
That said , ALL woman aren't like this, and you may have to (and most likely definitely will ) get played, or your heart broken multiple times before you find the right woman that does this for you.
When you do though, it will be automatic and un forced, and you will know and feel it.
And you wont have to be actually have to be paying any of her bills or anything to know this. either, but if you bump into this woman I speak of, you wouldn't care about doing it. (She would do it for you if it came down to it as well)
