Joe speaking from personal experience I can only say that after being brought up in the org you do tend to put up barriers between yourself and worldly people. As Legolas said we're taught that worldly people although well meaning are bad association, that their habits will rub off on us and bring us down to their level (what ever that level may be)
Dee's had 19 years of having that drummed into her so she might be behaving the same way. She might however go in the completely opposite direction, I know witnesses that have embraced the world once they've left.
For me it took months to accept that I was never going back and that the only way forward was to accept worldly people on their terms and that meant no more judging them but accepting them for who they are.
You sound alright, i wish I had had someone like you around when I first came out, it might have made things a little easier knowing there were genuine people out there.
Do us and Dee a favour though, tell her if she has internet access there's a whole load of people here in her shoes and that she can pop in and chat any time she likes, even if its just to talk fluff.
