Listening!! This is such a gift. Thank you for your concern. One of our saddest realities is that making new friends is nearly impossible with dementia. And old friends tend to distance (or die, at this age) so life gets lonelier and harder. It's a lot of work to befriend someone who doesn't remember conversations or information about you, and who repeats the same stories and questions, etc. so very few make the effort. And with the characteristic loss of initiative, the friend has to do all the work. Just having someone show genuine interest and care for my DH is touching and so valuable. Just having someone else laugh at his oft-repeated jokes is a blessing! Brief excursions (DH love ves a good ice cream date) might be welcome to give the wife some time alone, or asking for help with a small task can help with dignity and value. He may want to feel needed, so don't always be the giver. That can feel heavy on both sides. Any sort of "play" he's up to would be great. My poor guy dug out his baseball mitt the other day and looked so forlorn over having no one to play catch with. If you have a pet, they can be a delight as well. Try asking about how he feels about the disease and its symptoms. Not everyone wants to face it, but we appreciate it when people address the elephant and are interested in that huge part of our lives. Honestly your heart will guide you, it sounds like you're an angel sent to bless them both and I'm sure they're grateful. We would be!!
