How do I deal with my great-grandmother being so greedy?

It sounds like my grandma. It's a horrible situation to deal with. I am in the middle of getting my grandma out of my place since she takes my stuff and won't help with the expenses.

gothiccave, oh please tell us that Great-grandmother is helping financially with paying her fair share for living with you. Otherwise, maybe it is time for her to try out Independent Living/Assisted Living where she could be around people more close to her own generation where she would have more in common.

Well, you can understand why the others avoid her!

One piece of advice is to give up trying to reason with her when she is being unreasonable. Whether she has dementia or not, she sounds stubborn. The more you disagree with her, the more convinced she will be that she is right!

What conditions and diseases does she have? Is she in pain, like from arthritis? Pain can make anyone cranky. If she gets something for that, her disposition may improve.

my partner and I are her full time care givers
she gets more then myself and my partner combined in income and she still claims she should be giving her more money
her memory loss really is not that bad she remembers to feed her dogs when she has appointments and phone numbers

Great grandmother lives with you, right? Who else is in the house? Who is her primary caregiver?

Has GGM always been like this? What are some other examples of her greed?

Your profile says she has general age related decline. I wonder, though, whether dementia might be present. How is her memory? Her thinking in general?

I'd have to know a little more about this situation in order to advise you how to deal with it.

she did get cards and flowers from most of the family
she lives with myself and my partner because she is so difficult that most of the family will not deal with her

gothiccave, just curious if great-grandmother received any cards and gifts from anyone else in the family. If not, she could be so upset that she was forgotten and she took it out on you. Was it fair? Of course not.

Stop spending any money whatsoever on great-grandmother. Allow her own children (not grand-children, and certainly not great-grandchildren) to give her things. Live your life in a way that would make you proud if you were your own grandmother.

Dysfunctional families, elderly with dementia-break free so you don't repeat this when you get elderly.

Then, forgive her-she doesn't now how to behave anymore.

Hoping you can have a nice life in your future.
