It's a big move, a big decision.
My mother (now 90yo) started having frequent falls which lead to great difficulty getting around and additional injuries. Over time, she needed a greater level of care that could not be done at home.
She's now in assisted living. She's still sharp. She had COVID last fall.
She adjusted. She likes the company of the residents and the people who care for her. My two sisters live very close to where she lives.
She had a successful career and a difficult life. She's very resilient. She was a wonderful cook with four and then five children who worked full-time. She helped me to get sober. She's been sober for forty-one years.
People talk a lot about the necessity of taking care of yourself first. That might be the best thing for both of you.
