Dad moved into ALF 6 months ago. The first month I visited every day, often stopping by briefly after work (30 minutes to an hour). After the first month, he became active in activities and I began skipping a few days a week.
Now he has a g/f and is involved with activities and ALF outings. I have begun visiting him on weekends only now, but continue to call him every day.
I wonder if I can/should start skipping weekend visits, narrowing my visits to every other weekend. Before he moved into the ALF, he was living by himself 400 miles away. He now lives 3 miles from my house. I do not want him to feel like I am hovering over him, but I don't want him to feel like I am abandoning him.
If your dad isn't having any issues and is in pretty good mental and physical health, then just play it by ear. If you have any concerns about how he's doing, then maybe a short weekly visit is appropriate. You're lucky he's so plugged in to his new lifestyle. You obviously picked a great place for him to live!
BTW, I think it is way too cute he already has a girlfriend. He must be a catch!! ;-)
