My older sister has a son with some issues. He's 35 and has never worked and was homeless for a while and almost died. It was so hard on my sister and all of us. We love him but there are trust issues. He's been taking care of our mother and Mom pays him for driving her places and doing some chores around the house. I've had an argument with my sister because the son - my nephew - has Mom's credit card and uses it to shop for Mom. Sis and I are having tension between us because I don't totally trust my nephew. He tried to scam our mother out of some money a few years ago when he was homeless. He has not done this since he has lived with Mom - at least to my knowledge. But Mom said she wants her credit card back and it's making her anxious that the nephew has it. Mom has asked for it back and nephew says he needs to keep it so he can do her shopping. I feel like he should just borrow the card when he goes to the store and return it. My sister thinks he's reformed and should be trusted. I think this is unfair to my mother. It's so hard when these things come up in the family and having my nephew included in the caregiving of Mom seems like it mostly adds to the stress for me. I want to help him and therefore, my sister, but it's exhausting.
