In support group a friend's husband follows her everywhere. Is there a way to get her husband to stop?

I have heard of this by men after prostate surgery. I wonder if something is going on down there? won't hurt to consult with a urologist.

Can another person in the group redirect him?

We call it shadowing when he's following me around and vulturing (when he doesn't just follow me but then stands over me, not saying anything and not answering me if I speak to him). I know it shouldn't bother me, there's really no harm in it but it still drives me a bit nutz now and then. I try to redirect him to a seat to sit in or to an activity he can do like taking clothes out of the dryer or stacking books from one table to another. Putting his snacks from a big bag to a bunch of small bags etc... Any type of distraction seems to help de-fuse his obsession with me. Good luck. Patience, humor and self talk is what gets me through.

Sounds like Alzheimers to me. My mother used to do it to my father
