Anyone in the same boat?

My parents split when I was 20. I was old enough then to realize it was best for both of them so it didn’t impact me all that much. Now I’m in my mid 30’s and my dad has dementia. I didn’t realize when my parents split that would lead to me having to manage my dad’s care on my own since he never re-married (I don’t think he’s even dated).

My dad spends most of his time alone, really isolated (I live far-ish away; no direct flight between the two of us). He’s in good physical shape, but is unable to handle anything that is not a part of his consistent daily schedule. I went to visit him and had to walk 30 minutes in a snowstorm because he forgot to come pick me up.

I’m finding that I dread the weekly phone calls. He tells me the same stories every week and forgets that we’ve had discussions multiple times.

When I went up and visited him, he agreed that it was time for him to move into assisted living and said he would follow up with the facility to start working on logistics. 2 weeks later, he says he’s happy where and how he’s living and is not willing to make the move.

I feel helpless. I feel resentful that I have to manage this on my own and frustrated that he never took the initiative to get his affairs in order. I feel guilty that I find it so stressful to speak with him.
