Hi, Dixie, as the wife of a AH I can tell you that my mother in law is a great source of comfort and help for me. She would occasionally call me and ask how he was doing, but she always asked how me and kids were first. She made it clear that she was always there for all of us if we ever needed anything. To this day, I feel that her and I are the only two people in his life who feel the same about him and therefore no matter what happens I know she is in my corner. If I were you, I'd call your daughter in law and find out how SHE is and remind her that you are there for them if they need you. Just my two cents! Good luck, I'll keep you in my thoughts.
Jen
