TS,
By now you know how these folks are. It's all they know how to do.
I have a very good friend. (you probably know who I'm talking about), who won't invite me or wifey over for ANYTHING, (He knows damn well I'm doing much better since I'm out). He is way too scared to hear the "real" truth. He probably knows the real truth.
I'm convinced that "knowing" doesn't matter. Peple stay in for various reasons, and those reasons don't have to make logical sense. There is no reason to bang your head into a wall over it. It's a matter of cognitive dissonance and other forms of warped psychology.
Do yourself a huge favor and move on. You are in a good place. Please believe that.
