Brother's wife can't cope with his serious illness

I'M looking for clarity around a desperately sad situation with my brother and hope you can help. He’ in the early stages of a serious disease and recently his wife insisted that he was admitted to hospital.

- 

It's now been decided that once he’s discharged, he'll go straight to live in a care home.

My issue is that my sister-in-law keeps calling me, wanting to know all about my visits to my brother in hospital, yet she won't visit him herself.

I've reached the point where I've stopped taking her calls because it was becoming too frustrating, having to go over everything with her. It’s an awful situation for my brother and my heart breaks for him.

The positive news is he's beginning to feel much better on his new medication.
