If it was a route that looked good to me I would have kept riding it.
Everybody's different as far as riding with a group goes, I guess. I ride so much by myself and am so used to following my own agenda I can take or leave company. When I do share some of the road with another rider it can be interesting and for me it's always a casual meeting on the road. My problem is this: If I see a rider up the road and am able to chase them down, well they aren't gonna be a lot of fun to ride with. They can be a lot of fun to chase down.
I have met riders at intersections and formed a successful ride partnership. Or have had riders sit up and wait and vice versa and had good shared rides. I do enjoy meeting a young strong rider(s) (this sounds so masochistic) and having them make me suffer.
