My wife, age 74, has early stage dementia. She claims to be easily confused, cannot handle money, and states she has no desire to be intimate with me. However, I have recently discovered evidence of her having risky sexual behaviors with other men, and hoarding money. I am her caregiver, but having medical issues of my own, I occasionally must be absent for periods of time for medical procedures. She resists any other "caregivers" and is still able to drive. Any suggestions?
