(((((((Sitting)))))))
I don't have a clinical name for it. I do it too though. I think those of us who have survived abuse have this way about us. Like getting close to someone else feels good and scary and unfamiliar at the same time. For me, I also find that I know what to do with people when they are difficult or hard or inattentive. I don't know what to do with people if they are consistently nice or helpful or loving.
Take care.
