So is covert incest more rampant in single parent families is the important question. I think it's important maybe to kind of reclarify covert incest as a term used to describe what feels incestuous but isn't physical sexual contact or it might be more helpful for people to think about the fact that a child is playing in the role of a surrogant husband or wife. That maybe something that people can relate to better than covert incest. And so certainly in single parent families, there is going to be an absent parent and a sensitive attuned little boy, say for a single mother who's father is out of the picture, or mom is lonely, or sad because dad is, you know, left, he might naturally want to comfort her or he might want to step in and take over the role, and certainly she may want to invite that, but the fact that she's a single parent by itself doesn't mean that's going to happen, you know? As long as she's getting her adult needs met with other adults it becomes a natural barrier, so the child, the son might be very sweet and loving and say mom, I hope you have a better day, but he won't take over the role. We don't have any percentages. In fact, most of the people I work with have come from intact families although they were dysfunctional, so ironically in a more dysfunctional system in which the parents are together, which there's fighting going on constantly for example, there's more of a chance for the child to get used by one of the parents perhaps unintentionally, but nonetheless used to comfort me because your father and I fought, and now I want you to listen to my problems. And you can't go anywhere because you're my six year old little boy, and I know you love me, and you don't want mommy to hurt anymore. So we see alot of that kind of entrapment in families are not single parents.
