My husband knows he has dementia but expects me to never be affected by any of the difficulties. He says nasty comments if he hears my voice change, even if I have been patient for so long prior. He comes up with "solutions" for destructive behavior, even though it's the same solution that has failed 1,000 times before. He just calls me a b#tch and a liar when I tell him, for example, that he has broken something many times before and needs to do something a different way now. Signs to come get me don't work. I adapt to so much (!), but I don't know how to not get upset when he does something destructive again and refuses anything but his own crazy impossible "solutions."
