I think you should leave this situation alone. This woman does not seem to really be looking for any help.

The relationship sounds very co dependent in my view and not really abusive. While his behavior is not good it does seem that she is content with her relationship.

If middle class...upper class..or lower class..matters so much to her “image of herself” then I think she may have a self esteem problem.

Worrying or concerns about social standing is also a mental condition.
