I should have known when I was dating the woman who ended up being my wife and the egg donor of my children, when she said to me, "I'm fucked up" (referring to herself). I wanted to be the White Knight, but she turned out to be a subclinical sociopath. I never raised a hand to her, but she hit and slapped me, purposefully hit me with a car with such force that I went up onto the hood and slid up onto the windshield (and when I yelled out for her to stop the car, she sped up!), jumped on my back injuring my cervical spine, and had an affair with the guy who lived across the street (who also had a wife and three children of his own). I endured all this, because I knew that the abysmal Philadelphia Family Court system would never give a Father primary custody as long as she fought against that, so I stayed so that my children would not ever have to be in her custody without my protection. But when she continued to abscond for weeks at a time with my children, never telling me where they were, I had to put a stop to it. I had to file in court for custody. And in the end, I got only 50/50 custody, and the kids end up staying in her sole custody anyway half the time. So I had borne the thousand injuries of her for naught all that time. She ended up unilaterally making me a part-time Father anyway.
