Sorry for the loss of your grandmother. My 1st W didn't come to my grandmother's funeral, and later on my mother ended up temporarily paralyzed from the waist down due to ruptured discs impacting her spine. My aunt called 1st W because she didn't have my cell number. I got the same kind of text you did "Aunt called. Your mom is paralyzed." That was before BD, and she was busy with OM when aunt called. When I went up to take care of mom, 1st W had a great time with OM since I wasn't around.
Just shake your head and realize this isn't the person you married. Next time your W asks what you have planned, give her the same response. "I'm going out."
