Ok, you have decided the M is over. Now, you have to prove in court (you know, I know, everybody knows he cheated, but the court needs a real proof, not just phone calls) that he has strayed with this particular woman. How are you going to do this?
This is the time for you to calm down and let him "enjoy" OW. Don't threaten him with ANYTHING or else he will be extra cautious and you won't be able to get that proof.
I know I sound mean and manipulative, but that's what I would do if I decided to go that route: I would let them feel confortable to see each other for my own benefit. I decided not to go down that route 'cause I don't want to deal with the added pain of having to clash w/ OW.
I hope you take a few days to think about it and see if you are really up to it.
