Interesting article, Oddball; thank you for posting the link.
After the passing of my DH, I have chosen to be solo. Different people suggested that I try online dating but I have found that I can focus on consciously loving life, others and prayerfully thinking and loving the world itself.
I make the effort to meet and greet (with proper physical distancing, of course) others via a smile, a phone call, facetime or other communication.
I was aware of the challenges of lack of community when I moved from the property that DH and I had shared to a nearby home of my own. I chose to stay with a familiar community exchanging support with familiar friend and social networks, known contacts with businesses and professionals and the shared history of location. Moving to be with family would have meant starting to build a community all over again as family members had their own life to live with their own commitments in their own neighbourhoods.
The time may come when I need to move again to a more supportive residential setting and I am aware of that but for the foreseeable future, I will live with my little dog, cuddling/walking him every day and staying in daily touch with family and friends.
