Oh yes Teachername definitely a miss use of the term in that example
.
Well our ES's wife appears to be fine until she decides she no longer wants or needs you around Gonegirl. She has a history of this with her own P's and extended family members as well as friends.
With her P's and some extended family members, she severs contact, then resumes contact, then severs it and on it goes.
With us for which we are grateful, there's been no suggestion that she would ever want anything to do with us again. Which despite resulting in our estrangement with our son and only GC, is the better option for us.
But yes, I'd also agree that she's naturally bitchy.
