One common trend I see here is when they often will want to reject, in one form or another, the woman because they don't understand/comprehend that someone can be a jerk at times, but still be an overall good person and that our light and dark falls on a spectrum and that, scientifically, it's not an A or B thing.

Is this the "splitting" I keep reading about or something else? Like when that person they're trying to date suddenly becomes ALL bad because they did something subjectively 'bad' to the splitter (say the metro made them late for the date and they had to cancel last minute). All of them gets rejected and not that one situation.

Trying to help a friend and needing resources. Thanks!
