That's true. Women are better with expressing themselves through silence and with words, as compared to men. Thus, if you listen carefully and actively, you will know what qualities do women look for in men.
Women, essentially have a deeper emotional drive than men (this doesn't mean men are insensitive). This is primarily the reason why, it takes a long time for a woman to befriend a man, and even longer to make him a part of her life.
Women hold their emotions at the highest on the victory stand. It is something that they were born with, something that they cultivated (knowingly or unknowingly) and inevitably, it is the factor which emphasizes femininity. So, they just expect men to understand, and be insightful about their emotional side, and well may be a little more.
Your friendship has credibility, unlike the faux relationships one shares with general friends. So, if you have it in you to be honest, and upfront you stand a chance of winning her heart.
As men are the providers, protectors, and the possessors; women are the caretakers, nurturers, and life givers. Thus, they look for partners (reliable ones) who can protect what they care for, nurture, and give life to. Can't help it, it's their basic instinct.
The biggest mistake that men make is to offer solutions. Men have solutions for everything and anything in this world. Sadly, all any women expect, is to hear them out. Don't calm them down, let them vent it, and be a part of their excitement, without being judgmental or critical. Is that too much to ask?
Hearing out, what she has to say will help both of you make an emotional bond. If you can allow her to anchor her emotions in you, there is nothing more to what women really look for in men.
They want you to take calculated risks over impulsive, regrettable decisions, and facing your fears than running away from them.
Maybe girls, mostly teenagers, would be interested in a Prince charming. However, womanhood makes them realize that looks are just an illusion. So, what women look for in men, is exactly what a man would want from his woman.
