Hey L, just started reading your sitch. Sorry you're here.
It sure does seem like the vast majority of WAS's have an OP in the wings. I know I thought my W was the LAST person on Earth to, and so have many others. People grab anything when they fall, and I guess when people feel bad enough they do things that make them feel better no matter how destructive.
FWIW, I don't think people should be getting together with members of the OS when they are married. Play dates or not. Coworkers or not. That is not what people that want to tend to their garden do. So no matter what that isn't appropriate.
I'm not saying for sure there is an OW. It is possible though. Many things are possible. No matter what, it is a unfathomable loss and I'm sorry.
Tell me more about who you were before you met your H. I'm curious to know how you see yourself outside of this crisis. We're here for you!
