Oh boy where to being.

First, you need to slow down and think logically. You want to bust this OM and get him legally in trouble for adultery and have his kids taken away from him, yet you want to protect your wife who is guilty of the same??

Well, say you do all of this. What if his wife or he himself turns around and does the same thing to your W? Your wife is very not innocent in all of this. She is just as guilty as her OM. You are all about protecting her to make the path smooth and paved for her to come home. You think exposing JUST him which is not possible without exposing her, by the way, and destroying his family is going to make that path nice and smooth? No, it's going to put boulders in it.

If you are going to expose this, you are exposing them both as they are both equally guilty parties. Just know that. Don't think you messing with his family is going to protect your family in any way shape or form.

I know you re fueled by anger right now. Rightfully so. But I would be smart about this if your goal is not to let what your wife did get out. because she is as guilty as he is.
