The only way you can prevent backsliding is to be disciplined. You will feel like reverting to old ways when H acts like his old self. It happens. I kind of snapped at my W last night on our movie date because she gets so agitated and frustrated about every little thing before we get tickets, popcorn and get to our seats. I said "calm down" kind of harshly, but after a few minutes we both were relaxed and it passed.
Good luck and don't think there isn't a lot of hard work ahead. Keep referencing The Divorce Remedy or Divorce Busting, because you still can't change him, you can only change the way you interact with him!
