Dying of boredom

The total silence, the reproachful stare because I can't figure out what will entertain him, the complete lack of awareness of the state of the world, his family, me. Someone on this site said, wisely, we can't make them happy, only make them safe. But what do we do with our days while they sit and wait for us to make a meal, take them to the bathroom, switch the tv to another channel? He is too crippled by arthritis to get any meaningful activity ; we take a ten minute painstakingly slow stoll passing a house or two on our street. He walks so slowly I want to run away in frustration. I have found some youtube people who do very simple weight exercises with 2 pound dumbbells, but he won't look at the t.v.; he wants me to tell him each part of each exercise. I know he can't look at the tv and know what to do; and my explanations, if they are more than three words, make no sense. I am sure there is an existential play about my life. And I know that inside that crippled brain he is probably bored too, but I have given up trying to figure out how to alleviate his boredom. Or mine. I just visited a memory care facility that will probably be fine (after visiting at least a dozen or more, ranging from corporate owned to small 10 person, activity-less but caregiver rich places. I will be on their waiting list and hope I make it until they have a space, but fear I will just give up in the unending endless scorching days and put him somewhere just to have the burden gone. Thanks to all of you for listening.
