Dancer...thank you for your concern and your words of support. No, unfortunately, my MIL will not press charges probably unless she's really hurt by Robin. The Adult protective services won't step in unless she's willing to say something, which she isn't.
We can complain to them all day long but without her confirming anything is happening, it's our word against MIL's and Robin's. If it was MY Mother I would do things entirely differently, you know? Or at least try.
Keep praying for this family...it's so much appreciated.

Warm regards back at you, Dancer
