Friendships change for many reasons and transitioning is only one of them.
Over the years I've had friends, who like you and yours, spent a night every week for a decade or more doing things together. Then somehow it begins to slow down and eventually it's gone. Nothing lasts forever, not even friendships. Those that do are few and far between.
I can say that I have one friendship that has lasted for 60 years and another that is pushing 50. But all the others have faded into the past. New ones come, but I don't see them setting any records.
It's the way things go.
When things get tough you find out who true friends are.
