This is a tough one! I would not have my mom living with me. I would have insisted that she not waste her money by helping useless brothers who never did a good job managing money. That money would have paid for assisted living.
I would not do it again. I do love mom but this damaged our relationship. It puts a huge strain on a parent/child relationship. It’s too much pressure on the caregiver. It’s too hard for the parent to allow the child to have the upper hand. From what I have seen many times over, parents don’t want children telling them what to do, even if it is for their benefit.
