In our sitch, my W's affair was happening in her work place so I exposed to co-workers. It was then no longer a big secrete.
I made the decision to NOT expose the affair to my family because I knew it would be that much harder to reconcile after and get them to accept it.
For me there are different levels of exposer. I only went as far as exposing to co-workers and OMW. In some cases there is not a OMW but at the very least I think the cheating spouse should know that you know what is going on and will not stand for it. The cheating spouse will get angry and will deny but as my W put it - it became that much harder to carry on the affair knowing that I knew and would do what it take to end it. My W always said and truly I did not care for her but when I stood up to the affair she for once felt as if I did.
