Why is it guys have to go through social proof to deem them safe, but women don't?

Why in dating do guys have to go through a vetting process to deem them safe but women don’t. Like I just came from a messed up relationship where before hand I was single for many years and I would hear people say that when women don’t see you with any one it’s stranger danger or something is wrong with you much of this I let go in one ear and out the other because I know the kind of good person I am and my poor social skills are the main reason I don’t have people around me. But anyways with this girl she turned out to be abusive physically and verbally she never actually cared about me even though I was fully invested In her. She would hit me in the head when she got upset, actually her whole family had a history of violence. Her sister threatened to kill me when I wanted to break up with her because of the craziness.
