I’m on both sides of this, as someone who is losing a loved one to dementia and also as someone with memory issues due to chronic illness. One thing I think Carolyn missed is that there may well be fear behind his actions. As someone who lost a (presumably loved) parent to profound memory loss, seeing what looks like the early pattern occurring in his spouse may well be triggering for him in ways he doesn’t even understand. And when we’re triggered, we often unconsciously react by trying to shut down the thing that’s frightening us.
