I might be crazy to think this so soon, but it really does appear as though my H is finished with OW. He keeps saying things like "How could I have been so stupid?" etc. I actually don't think he would go there again with her... But, what I worry about is that the vulnerability is still there that lead him down that road in the first place. He is working on that in IC, and I know he is sincere in wanting to get that figured out.
Sorry to hijack your thread with my fears... but your perspective is very helpful to me.
Also, Pearl emailed me some quotes from a book by Susan Forward (I don't recall the name of it) but it talked about trusting yourself as being the ultimate goal... to trust yourself in your own ability to confront lying if it happens again, to make choices for yourself, to know what you need etc. That makes sense to me too. You made some good points about what we have been through giving us the experience to know what we are facing if it happens again. I have to trust that.
My H also knows if this happens again I'm done. I've made that very clear.
