Life is tough sometimes.
Every now and then, life tends to throw you a curveball and a woman wants to be able to rely on her man to remain strong no matter what happens.
She doesn’t want to have to be the strong one or “the man” and take care of a scared, sensitive or insecure guy who can’t handle the pressures of life as a human being. She wants to be able to relax into being the more emotionally sensitive and vulnerable one, rather than having to be strong for her guy because he is weak.
All across the world, women are naturally attracted to the emotional strength in men (e.g. confidence, determination, high self-esteem, calm under pressure, etc) and turned off by the weakness (e.g. insecurity, shyness, anxiety, nervousness, etc).
