I was terrible at controlling my responses to the A until I did. Once I controlled my responding and only had to deal with him on occassion I learned that nothing had changed. His responses were predictable and I couldn't win an argument. I only ended up frustrated when I tried. I learned that I could relax and not respond. In time, my mind stopped spinning out all the things I want him to "get" and figured out I was better off letting go. Keep working on it.!
