He has lived in my home 10 yrs. I pay his bills and balance his checkbook because he is having difficulty with these tasks. He was diagnosed w/ dementia 10 years ago but is active and fiercely independent. He has recently begun to make completely false statements that he truly believes are truth. I can clearly see his reasoning issues are progressing, although I have seen him pull together for short periods of time and appear to be alert and clear headed so many people do not seem aware of the issues he has (including this woman apparently).
My concerns are for his financial well being since the 77 year old woman is in poor health. I don't want his funds to be exhausted by a 'new wife' so that he will not have the money to care for himself when his needs are beyond my capacity as his daughter. Since he lives in my home in an in-law suite we set up I could not allow them to live there but I am concerned that he would not be able to function appropriately if he tried to move somewhere and I wasn't able to watch over him behind the scenes as I do now. I have DPOA but what will happen if he marries.? Will I lose the capacity to make his decisions? How should I approach this with him since he is not able to understand if I try to reason with him? Anyone been through something like this?
