Tresspasser... I think this is why the phrase "I could tell you, but I'd have to kill you" came to pass. Use a the right accent, a twinkle in your eye, and raise an eyebrow. Be mysterious. Then either walk off or change the topic =)

I am at a point where this couple (who knew me when I was "healthy and fit for society) now want to get together. Running into people for 5 min or less convo is one thing... purposely going over to visit people I used to know .... wtf do i say to them? Most my life is a secret from people because I have learned how easily info falls into the wrong hands. The rest is like you just explained - having to tell them things that is none of their business.
I thought I wanted to see them, too - until i gave it some thought. *scratches head*. now I don't know how to get out of it.
