He decided to close the pool yesterday, It is wrong with water still in pipes but he argues with me that it is ok. He thinks as long as he did something it is fine. He insisted on doing the taxes, he didn't get it right. He now thinks if something breaks it is ok the way it is and we should just leave it. He sits in front of the computer all morning and the tv in the afternoon. He watches the same NCIS and Law and Order and similar shows over and over, even if they were on just the day before. I don't mind that but he wants me to sit with him and I'm going out of my mind. He was outgoing when we met 39 years ago but as time went on he became more into himself. He loved tennis, golf, skiing (snow) but now he won't do anything not even a short walk, he claims his feet hurt. I have taken him to Dr. after Dr. and they all refer him to someone else. Nothing shows on MRI. He can't speak well and is very forgetful. Last week he called me by our last name, I am assuming it is because he forgot my first name. We spend our days in silence because he doesn't talk and if I ask questions he gives me some off the wall answer that frustrates me to no end. I am not a good caregiver, he has no family to help, our only child died, I have 2 children that live in other states. Our neighbors are nice enough to try talking with him but he mostly ignores them so they leave. He still wants to drive, I gave his car to a relative to keep so maybe he would not drive but I will go looking for him and he has taken our only car and left the house without saying a word, mostly he likes Wal Mart.There is one person he likes at church and if he goes there and they are not there he will return home for that reason. He is 68, his father died a few years back and his Mother died this year, she was very similar. I wonder if he will live into his 80's or almost 90 like his Mother. I would also like to say my husband was a pilot, had a master in aerospace engineering but I guess mental illness doesn't care.
