A hour isn't that far at all. I drive 45 minutes to work every day. Make a plan to go have dinner with him once a week. Bring him dinner and clean up afterwards. It will make a world of difference knowing that you're coming and that he can talk to you (or maybe not talk, but just be around someone who he doesn't have to explain stuff to). It's lonely, exhausting and stressful being a caregiver, and grieving the life you had before. Just sitting and eating might be what he needs. My mom is my dad's caregiver. Before he had cancer, she had a heart attack and triple bypass. She's the glue of our family. She makes him dinner every night. She makes him coffee every morning. They watch the news together. He was lost without her, and I came home from college to help him while she was recovering.
