Thanks for all your kind words - things will work out with my Mother-in-law. We are not being pushed around by my Brother-in-law(*who definitely will get his one day), and we will be staying with her unless she moves before Christmas which is unlikely. If she moves we will still be staying in her condo as she is locked into the lease for at least 90 days.
Now I am off to make a Sunday brunch of banana muffins, bacon and eggs. More comfort food!
