i get what you mean when you say she is sabotaging herself... and i agree with you... she cannot get out of her own way... it's like that line near the end of Breakfast at Tiffany's when Paul tells Holly, "...no matter where you run, you just end up running into yourself.”
you cannot trust your WW... you ought to be there when she moves out... i would not give her the opportunity to take further advantage of you... and she will... don't be so vanilla all of the time... you are getting mixed messages here... "stand your ground," "take the high road," etc., etc.,
because it is you, i say to go toward the stand-your-ground mentality, because that is opposite of what you naturally do when it comes to your WW... mis dos centavos--
