1. Don't expose if you can't follow through with the consequences 2. He can tell you are weak on the follow through so he's going to push you hard there
I do think your exposure did make a dent earlier. I think his public image is important to him. You may not have convinced him infidelity is harmful and childish, but you did shake him up and put a stop to his parading the affair all over town with pride.
Your actions didn't end the affair, but I definitely think he's been forced to rethink his strategy. THAT came about because you exposed the affair so well. If you had sat back and did nothing you would likley be miserable and depressed right now... And he would be pursuing OW in the open and enjoying that love nest still...
You stopped all that... and I think it put you closer to saving your marriage because of it.
