anthony,
i have been out of the dating circle for years since i married my wife in '97. however, i can state that i've seen others go through similar situations as yourself. and even though i'm not a psychiatrist by any means, domination, manipulation and control are all factors of a sociopathic personality. be careful as to the extent that you allow this person to play games, if you can at all help it. it can be very dangerous and destructive behavior. and with children involved, things can get messy real quick as you've all ready previously noted. i have a quote that i live by. "you guard your own house. you guard your own yard. when trouble comes knocking at your door, you squash it like a cockroach before it starts to breed." good luck paison.
