I totally agree with dday. Showing that kind of emotion validates their belief that they are doing the right thing. It also often lets them feel in control which they crave.
Not letting them feel that way has a totally different effect than you might think. Change your thoughts and see what effect it has.
They do care though. It drives them nuts they care so much. As if they are unable to stop thinking about it is almost a release for them to treat us poorly. Stop that cycle and you'll start to see some different results.
