Recently my 80 year old father who had been diagnosed with mild dementia has become fixated on his finances. So much so that he is convinced that my mother has been stealing his money for years (which is not true and we have presented attorneys, case workers, psychiatrists, etc. to explain to him otherwise but he is convinced of this.) And it has now culminated into his request for a divorce. My mother who is his primary caregiver is fed up and doesn't want to argue with him anymore and is granting his request. I understand that this is quite common but I was hoping to get any further insight from others that might have been in the same position. Thank you.
