A lot of women have cluster B personality disorders which can be extremely scary. I knew a girl in college with legit bipolarism and I saw her argue with her boyfriend. It escalated to the point where she gripped a mirrored closet siding door, ripped it out of the wall, and through it at her bf (she was over 6ft tall and big and just went bananas- it was nuts!) Another time she got mad at me for something dumb and was threatening to stab me at a party. Absolutely insane. A lot of women are totally insane.
