You are doing great! There is no guarentee that he won't go back to the OW again. That is what makes it so difficult. I know in my sitch the OW finally got fed up with my H going back and forth between the two of us that he dumped him. I can't blame her either. He was messing with us both and since she doesn't have any committment to him, it was better for her to move on.
I was be extremely cautious and have strict guidlines. My H knew that one of us would leave if I found out he had any communication with the OW. I also had a plan that if there was a night that he didn't come home by 9pm, I was going to pack his stuff and put it in the garage and have a sticky note on the door saying "goodbye." He didn't know this was my plan.
If you can talk to him about going to Retro, I think that would be great. I asked my H about it this past weekend and he shot that idea down really fast. The next weekend in my area isn't until May, so I am hoping that he might change his mind.
Good luck! I know the drama is too much to take at times.
