AS: "Man that is so rude. Just banging them, wow. I would not dignify that with a response. Next time she says something like this just say "I don't feel comfortable discussing my personal life with you." That'll make her head spin!
AS is right here. I've noticed is that the new dynamics in these situations where an SO has pulled away. I've seen this before in many breakups in prior relationships, as well as with my WAW . I'm willing to bet if you ask the W anything personal that's exactly how they will respond to you with ambiguity. Respond to them back this way not only will she understand it but yes it will make their head spin. Never entertain or justify explaining crazy delusional thoughts from another person that wants to have nothing to do with you. Your time, and your well being is much more important.
As a matter of fact make sure you rehearse and incorporate this statement into all of your personal responses to personal questions. Let them understand what guarded abiguity feels like. They understand this very well.
