I don't understand

why when you tell you someone you can't/won't talk about something, that they insist on proceeding. I knew that having any semblance of a discussion would only end up in a fight and therefore I didn't want to go there. I was pressed into it, ended up in the fight I didn't want to have, and now I'm reworking my life to avoid this person. Stress Dieting - I don't recommend it! I wish I were strong and could just let it go, instead of internalizing it. Going over and over the words spoken - of course, later I came up with several good responses that may have ended things, but I was way too emotional at the time to think clearly. Ugh -my stomach hurts.
