What is best for Dad?

We have been forced to ask the hard question now for quite a while--what is best for Dad? It is an continual giving up our own personal desires on behalf of Dad's best interests. I have come to realize that at Dad's current state of mind, it is too confusing for me to visit him without bringing Mom along. He seems to associate with seeing me that Mom should be present, too. And as for visits with my children, it is a catch-22; he seems bothered with me if I don't bring all three along, but when we all come to see him, he quickly tires of their "child-like" behavior in his small and confined room.
It is becoming increasingly difficult to leave him. He gets very insistent on going along when we prepare to leave. He told me on Sunday that he wanted to head to Pikeville--it would only be 120 miles. It is very rare to leave him in a peaceful state where he is content be "left behind."
I must repeat to myself over and over-- this is what is best for Dad right now. It is out of my hands. But Dad is never out of the hands of the Almighty God. I can rest in that truth.
