I had to place my husband who has Alzheimer's in a family care home when he suffered a couple of bouts of pneumonia and became too weak to get out of bed. Now he is friendly and cheerful with his other visitors but barely speaks to me. I get reports from his visiting nurse and social worker of the cute/clever things he says to them. It is very hurtful, and I sometimes think of stopping my visits with him. I have to force myself to go even though we usually just sit and watch TV for a couple of hours. I was his caregiver for nine years, changed his diapers, washed his soiled linens, cooked and cleaned for him. When is enough enough?BTW, I'm 89 years old.
You matter too.
Me, I would not sit there for 2hrs if he was not talking to me. If within a half hour he did not respond to me, I would kiss him on the cheek and say "I will come again when your in the mood to talk". Their days run into each other, they have no conception of time. You could be there every day but they will tell someone they have not seen u in weeks. Take some time off. If you have been going everyday, cut back. And when u visit, you don't need to stay more than an hour.
You describe your husband as content without you. There is utterly no reason to go to watch TV with him. Cut down on visits both in frequency and in length of time you spend and assess the results.
Best to you. Concentrate of the happy memories of a lifetime, not on the caregiving, if you are able.
That being said, you've done yeoman's work in caring for him all those years! Kudos to you. I'm not sure how often you visit so maybe you can cut back on that. If the family care home ever has activities, maybe go when there's something you can both do together.
Be kind to yourself and do lots of self-care! Treat yourself to things that bring you joy and peace.
