Thanks for all the great advice. I'm not sure what tactic I will finally take. One reason I don't just up and move away is that I have a nephew here who needs me to stick around because his home life is really crappy. So, what I have done is travel a lot - and that sort of keeps people at bay because they don't really know when I am in town or not. And I might work out of town on a temporary basis - which would also keep people out of my hair because they can assume I'm going to meeting down there.
As far as a relationship goes, I would just have to be up front with whomever I am with about my situation and the need to be discreet. I wouldn't have him meet my family until after it was more serious - like we were married. :-) And Flipper is right - if I want a new life, I will need to do many things privately and secretly. I just have to get brave enough to do it, I guess.
I do like the suggestion of being a spy though. I do want to keep in touch with things enough to know what is going on, and what is being taught to my nephew. I think children need moral direction, but obviously, I'm not interested in supporting twisted thinking that might arise from his situation either.
Thanks for the support everyone!
