i've watched my son's AD go from person to person, place to place for about 20 years now. he's never had his own home as long as i've known him - always lived with someone else be that a gf, his parents, a friend. he just has a gypsy lifestyle - he stays till he wears out his welcome and then he moves on to someone else.
my AS does that but more on the emotional side. he's always looking for someone new to support his lifestyle and will come up with the wildest stories to make people open up their lives to him. its like he's always looking for a replacement family becuase he sees the problem as us not him. of course the problems follow him and eventually they figure it out and distance themselves from him.
