Is she the mother to any of your grandchildren? I had a DIL with similar problems, but unfortunately even though she’s mt ex DIL, I still have to endure drama to see the kids.
There is one grandson and he is now grown.
Unfortunately, her behavior has had an adverse effect upon his life.
It’s a long sad story that I don’t want to get into here.
It was really hard watching it all when he was younger.
I feel for you and understand how awful it is.
