Your situation sounds so much like ours. Been married 49 years and I’m just not sure the right path to take - let things continue as they are, or seek more help, possibly get a very scary diagnosis for which little medical help is possible, and demoralize someone who has been so strong all his life, even further. He is aware of his memory issues…ran his own company, always handled our finances, and I now am doing the same thing you are…following along, trying to be sure bills are paid and commitments are fulfilled. I have no advice for you, only a hug.
