I term'd a dcg a couple of months ago for similar behaviors - I just couldn't leave the room without hearing another of her "victims" scream - it was terrible. Lots of explaining to the other dcps.....AND it was hard b/c I adored her, but her Mom was in complete denial and was beginning to question ME and whether I was being truthful. I cannot explain to you the RELIEF on the faces of my other dcps when they found out she would no longer be with us. The days are peaceful now.
Good luck!
