I've considered hiring a second person just to entertain my husband a couple days a week. Any suggestions?

My husband has ALZ and I am his sole caregiver. We get eleven hours a week of help from the VA. Our helper is wonderful with him and helps me a great deal. But she has a full time job which often requires her to work at times she is supposed to be with us. I'm not upset about that, but it makes it difficult for me. My husband constantly wants to go somewhere and reacts like a child when I can't take him places. He's pretty self centered and doesn't care how tired/sick I am. This has been going on for over four years and I have just about reached the point where I want to run away. I love him and don't want him to be unhappy. I know he would be heartbroken if I put him in a facility. I've considered hiring a second person just to entertain him a couple days a week. Any suggestions? Thank you.
