EDIT: prohibiting further interactions (and abuse!)
The last resort - as we cannot force people to own thier behavior nor change it - is isolation.
Hopefully, the other people in your circle - social, family, work, community - will do the same.
As it is one of the great crimes in life that we neither advise others of their wrongdoing
nor make them suffer any consequences, that we presume the beahavior may go away on its own.
It may but that is unlikely, so we must do what we can to alter the poor momemtum
in which the selfish and abusive may engage.
