Sticky dilemma about a "friend" with a sordid past

[Irulan]

First of all AA is for alcoholics, not compulsive liars or con people. Sure those things can all go together, but I call BS on it. If the guy were REALLY working a program the first thing he would do is makes some sort of amends to all the people he's screwed over the years. Someone can go to all the meetings in the world, and give it lots of lip service, but one has ago actually work the program, not just tell the world that you are going to meetings. There's a lot more to it than quitting the booze.

Second I agree with Tulip that "perfectly innocent" is a stretch. Tulip is right in that if you want to remain social, there is a very fine line you need to walk to protect yourself.
