My mom prepaid for her to be in the Mausoleum w/my sister when she passed in 1975. My mom is currently terminal & when I bring up the issue about what the cost will be be when it’s her time to go in w/my sister she says “don’t worry it’s all taken care of”. But IT’S Not. I called the cemetery and asked if there are going to be any fees to bury my mom’s ashes (she wants to be cremated I know that) in w/my sister. The man said he would look it up & found that it will cost between $3700-$4000 to do it. Money which I do NOT HAVE. My mother has no savings, no life insurance. All she has is about $200 in her checking account after her bills are paid. She does have a reverse mortgage where she could ask for money there, but she gets mad at me when I bring the subject up. I don’t want to upset her, but I’m angry at her because she would die & leave me w/the extreme stress of not having any money to do anything w/her body. How can I approach her about this & what should I say?
