You know those "tolls" they take to see what women find the most attractive in a man? If memory serves, it is usually confidence close to the top of that list.
For the most part, I think it has to be that inner, true, self-confidence and not that "showy" stuff. Occasionally, a man might have to pretend he's more confident than he really feels, but what really turns most women off (I think) is the type who brags to make himself look good.
A word of caution, do not expect anything from her. Never go expecting a response from her. If you do, you'll be setting yourself up for disappointment. Don't try to to read any meaning into whatever she says or does, okay?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
