Helpme12, don't worry about hijacking this post. All good stuff because I'm interested too in BPD since many of those behaviours are relatable. Seems to me NGS and BPD are a natural combo like anxious/avoidant attachment. In any event, I think its about what you can live with. If my W's new norm is to try to cross a boundary once a month, cooling down the same day, I could live with that. If it's complaining about things because she has low tolerance (and she does) but doesn't direct that frustration to me or the kids, I could live with that.
It's something I need to wait and see because I don't know how much of this she brought to R versus NGS created by me. Maybe nothing of W will change even thought NGS is no more. I can only hope that is not true and stay positive that my changes will impact her in some way. MWD even talks about this in her "Takes One to Tango" concept.
