I wouldn't be surprised at ALL if your H tried to push your buttons! It seems like some weird subconscious WAH trick that they like to pull, and then the second we show any emotion, they can say we haven't changed :).
Sounds you are emotionally well-prepared for it though!
So I keep going on about this "as-if" model I found on one of the forums, but I think it could be useful here too. The idea is that once you feel like your changes have taken real hold, and are a permanent part of who you are, you think about each of the possible scenarios that your H could put you in, and how you will use your new "as-if" model to deal with them. I had a hard time doing this as I just couldn't face the idea that he could say the D word to me. He actually did say that word for the first time last week, and I didn't do THAT bad with it, but I could have done better. I think, especially if you're in between periods of contact, it's really helpful to do this...I think it helped me to react better than I would have otherwise, even if I still wasn't as good as I could have been!
