He says our Mom only wants her own children to take care of her, not a nurse or caregiver. My brother is single, is an RN, and has no children. I’m married, have three very young children (that I’m trying to teach with distance learning), and am also exhausted. My husband and I offered to pay all the costs for my Mom’s care, but they will only accept care from me, personally. They say it’s my duty as a daughter. Am I being selfish?
