I've read two BPD books. Going to therapy.
But what we really and truly need is a guide to handling her abusive behavior in THIS setting where validation and empathy won't work. Did I miss this in the lessons?
How do we handle excessive angry phone calls? And texts? And yelling in public in front of the children? And the children telling is about abuse in their other home? We usually respond with silence. We pick and choose our battles. But nothing ever feels right. I suppose it never will.
One technique my SO uses is to only communicate via email ONLY (phone if legitimate emergency only and no texting).
Communicating via email does several things... .
It slows everything down you can read the message and digest it. You can respond on your own time, I remember one member said that they wait a minimum of 24 hours before responding. Is the email something related to the kids or is it just a verbal attack? If it's something legit regarding the kids then take your time and think about your response. Don't just give your usual knee jerk response. Try to keep your response short and polite. If it's a verbal attack or other nonsense then just don't respond.
Communication via email also creates documentation of your interactions with the ex you might need that for various things... .courts, police, related to kids education, therapist... .you never know.
Communication via email also takes some of the emotion out of the interaction so you are able to stay calm and cool and respond from that place rather than hot and emotional.
My SO over time has been able to minimize contact. He doesn't engage in the games and she doesn't get the drama she feeds on so interacting with him isn't as interesting, as satisfying, or as exciting.
Phone and texting all goes by too fast you're often giving knee jerk responses, things escalate because emotions are high and there is no time to really think about your response or whether you need to respond at all. Phone and texting can also be intrusive (my SO's uBPDxw practically stalks her children via cell phone and they like Pavlov's Dog are trained to always answer... .20 million times a day... .we have been working to help them create some boundaries around the phones but they have to deal with the FOG (fear, obligation & guilt) so it isn't a simple thing to just turn off the phone.
Sorry got a little side tracked
As far as the public YELLING I know other members have used recording devices to deter that kind of behavior. Hopefully someone who has can speak to that. You could ignore her and just go on your way - set a boundary. Tell her if she continues to yell that you will leave... .if she keeps going... .then leave. Lastly, you could tell her that if she continues you will call the police... .if she continues call the police if things escalate to a place where you feel this is warranted.
I know how frustrating all of this is but there are ways to improve things. Remember we can't change or control the ex's we can only change and control ourselves. So maybe observe what you and your husband are doing during these interactions what can you both change to get a different result or shift how you feel about the interaction?
The 2 toughest things for me have been letting go of trying to control things with the ex and letting go of my anger. It took awhile and a lot of wasted energy and frustration before I finally was able to let go. I have been a lot happier and feel better by making those 2 changes in myself. :)o I think the ex does despicable things you bet but trying to control her is futile (the exception would be if she put her kids in danger) and getting angry is only hurting me neither was worth my energy.
I know other members will have other suggestions for you.
Hang in there.
