are we abandoning son if we suggest she take a break from the family until she is better able to control her emotional outbursts (which always come with an apology to her spouse but to no one else)?
Seems the best long term approach is draw a line without anger regarding acceptable and unacceptable behaviors is the best tactic for the system, but I fear alienating son or losing him altogether.
Thank you for any advice you can give... .
I’m sorry that your daughter in law is vilifying your partner, that can’t be fun. When you say "draw a line", do you mean setting healthy boundaries ? Boundary setting is the recommended approach. But it needs to be done with care, there is advise on this website on how to do that.
Also you mentioned “until she changes”. If she is truely BPD, then change is highly unlikely. Here the recommended approach is to use validating techniques such as S.E.T. to get the best out of your relationship. Again there’s advise on this website on how that works. Welcome to this site, and keep us posted on your progress.
