I remember that when I was first learning how to date, women would seek emotional intimacy and support on the date by telling me something that was making them emotionally vulnerable, but whenever I'd offer up any of my own to commiserate, it would give her the major ick. I then noticed this more and more with women in other parts of my life like platonic friends.

With very few exceptions, every woman in my life has had an extremely low tolerance of me sharing any vulnerability or seeking emotional support. They only want me around when I'm fun and entertaining. In fact, I finally shared a minor vulnerability with a girl I'd been dating for over month recently, and she explicitly broke up with me over it despite that very day constantly talking about her not interested in dating anyone else but me.

Women have a very low tolerance for male sadness.
