Take it from someone whose spouse did cheat. At some point you forgive and heal. My W had an A with her boss if you recall. Sure it hurt like hell, but at some point you can't let it run your life.
The OW is not entirely at fault. It takes two to tango. It's your H's choice. Free will. Again, you can't control what other people do. We told you a long time ago that you will start to lose your son, you haven't listened and now he's slipping away.
When are you going to start healing? You obviously can't do it with your H since he's not there. So what are you going to do?
Stop with the obsessing. It's like a broken record with you.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
