Sorry if this is too close to the other thread but it got me thinking.
There was that ad campaign showing domestic violence happening as if under people's noses and people ignoring it.
What are you supposed to do if you know someone is in that situation and s/he refuses to change anything but expects you to go on as normal when the partner is around? Are you supposed to pretend everything's fine? Do you put her at risk iof more violence by behaving differently to the partner? Do you avoid them and leave her alienated and alone? It must be quite draining being the impotent shoulder to cry on - does there come a time when you have to cut ties?
