I see why friends who are busy with family would not have time to go out, but those in the middle of a divorce should be prime material for drowning a few beers together.
There is an incredible amount of stress following a divorce. What will happen with the kids. Where will everyone live. Can I afford to live the same life style. Who will our friends choose. And probably 100 things I have forgotten. I was not the same person after divorcing for I would say about 3 years. I felt out of place. Lost. Certainly not wanting to go grab a beer. It was not a celebration and if anything for a long time one feels like they had failed at something. So I can see how anyone going through a divorce is high risk for social isolation.
