I'm a Duge Houser, I'd Drop Anything and Be There for You

My girl friend's uncle has staged for bone and brain cancer, and she's going to visit him next week. She wants me to go to northern michigan with her and her mam for nine days. But i can't bring the cat because her mamma's lurgicos. So am i a bad person for wanting stay and take care of my cat? Should i be more considerate? And do anything possible for her. If your family member was dying, i'd drop anything and be there for you but it's not quite that simple. Your wisdom would be greatly appreciated.
