I'm glad that you realize that you still need to hold tight. Likely, there will be some vacillation from him as his head and heart become pulled in two directions. I'm sure the OW is turning the screws BIG TIME! I'm gonna guess there are some fights going on between the two of them right now. YOU make sense to be his wife. You are the mother of his children and you have a history together. Ultimately, it's his head, and that logic, that must prevail. I think it will.
Your H is finally coming to grips with what he stands to lose. As the luster wears off his relationship with the OW, he's going to see her for the flawed person that she is. Meanwhile, you have stayed strong- and that's very attractive to him!
I do agree that if, or rather, WHEN ;), you reconcile you should move. There are waaaayyy too many triggers where you live now. What you both need is a fresh start- a new home for your new marriage and life together. The difference this time? Now you know how do do it right....
