My mother in law talks obsessively about money. Since she has become less mobile, she has given me her debit card to collect her some cash when I go to the bank. Since her dementia has started and she is rapidly going downhill, she has started to say that I am keeping things from her, that she is not getting her letters from the bank, etc. In September 2014, at her request, we prepared a letter to her banks asking for evidence of her holdings. All but one duly sent the information TO HER, which she opened and then hid away. She then asked me to put down where the various accounts were and gave me all the envelopes. For some reason she has kept her October 2014 bank statement hidden, and continues to claim that she has not received it. Despite having done as she asked, she is now insisting that I am hiding her money, dipping into her accounts and keeping secrets from her. I have tried to sit her down and explain, and even offered to get professional help, if she does not understand. Her response is to shout at me and steal keys to a bureau which will be returned when she knows about her finances! I am at a loss how to proceed, as the abuse is becoming more violent, and I am not sure who best to contact about this. Thanks.
