That's a big part of the problem I am having is trying to set the boundaries. This particular person will change topics and turn conversations towards certain topics. It will also jump from subject to unrelated subject. So it's been hard. This person absolutely has mental issues and refuses to even see or talk to a doctor about it so we are talking about switching topics/going from happy to mad the way you would flip a light switch. I think if the topic of my eating habits/weight/health comes popping up I am just going to have to say "I don't want to talk about that" and walk away.
