I see your point. You're basically stating that compassion, when skillfully used, is an effective antidote for the interpersonal relational challenges of having a BPD spouse, right? But I can't agree with that.
Love and compassion will help with any relationship and are especially helpful with a BPD loved one. It's not an antidote, though. Love helps with BPD just like money helps with health problems. Money can be used to pay for appointments, treatments, buy prescriptions, etc. But neither love nor money will guarantee a solution.
My BPD daughter hated me most of her life. She made every possible mistake as a teen and because my ex-wife was also BPD, I had to be the adult in the room. Not that my ex couldn't make decisions, but my kid knew mom was weak and would give in, so she attacked her relentlessly.
Every argument between them would eventually end with, "Go ask your dad, I don't care." So I had to be the bad guy, which I was fine with 100% of the time. The kid had to learn right from wrong and therapists were adamant about standing your ground. So I did and she hated me.
Yet every single time she was in trouble (always self-induced through bad decisions), she called me because she knew I'd show up and fight for her.
This continued throughout her teens and early 20's, until she finally got the right therapist. And once the therapist pointed out that I always showed up, always fought her battles, my kid apologized and our relationship has been great ever since.
Because that's the whole source of instability- I called it abandonment and maybe that's not technically the right word. But once a BPD realizes that you have their back no matter what, the dysfunction disappears.
Now, others in our family are now painted black and put through the ringer at times, but my kid and I continue to have a good relationship because of that one simple fact. When she needs someone, dad will be there no matter what.
After our separation, my ex had painted me black and it was basically the same situation. But over time, we moved past that to where my ex realized that I was an ally. She's untreated and in denial, but she knows that if she reaches out I'll show up however I can. And that ended 100% of the drama between us.
That's because not feeling loved is NOT the only source of ALL interpersonal conflict that a BPD spouse has with their partner. Any unresolved conflict will eventually lead to an internal dispute, which then may lead to the BPD spouse acting out.
My wife doesn't feel threatened with abandonment so often. She can get aggressive because of minor things that make her feel unworthy, but in the rare moments in which she did feel a real abandonment threat, she actually reacted in a very warm and kind way. I think it's the other way around. The more she feels safe and loved, the more she is likely to lash out. Simply because it's safe to do it. This is why I don't cuddle with her anymore. Every time I did it, the next day would be a nightmare.
There's two different things happening here. First is when your wife gets aggressive over minor stuff...but that's not true. You see the minor thing but she's seen 50 things in a disordered state that tells her you've been plotting and scheming against her. That's the illness and that's where having her back completely changes things.
Again, abandonment may not be a perfect word but that's what it is, she feels slighted or less than so she lashes out.
The other thing you're describing, when you're loving and she lashes out shortly thereafter, is an extension of those 50 things she's secretly mad about. She's mad, you're loving, and she enjoys it until she has time to reflect. Then she decides that your actions were because you're clearly guilty of whatever she's thinking and the big guns come out.
On the other hand, if my behavior does seriously indicate that I'm completely detached, she cools off and gradually cuts off the crazy behavior. She begins by using little pull strategies, such as being nude all day or saying that she is unwell so that I take care of her. But if that doesn't work, then she completely unflips and reverts from an entitled bully into a fragile and affectionate person. So I think the real fear of abandonment does not make her aggressive; it makes her calm.
Here you're actually talking about a boundary without putting a name to it. She wants to manipulate in order to punish you, but then realizes you're pulling away so she cuts it off and reverses course. During that time though, she's becoming dysregulated because you're distant and if you don't swoop back in....boom.
In both of these scenarios, it's a push/pull dynamic without ever fully resetting and getting back to just being there for each other. That's the battle, finding how to do that when the wheels fly off the bus.
With all the BPDs in my life (my ex wife's side of the family, a few other relatives), I've found that being proactive and letting them see that I have their backs no matter what diffuses all that drama and anxiousness. Because as soon as they feel even a tiny bit slighted or crossed, things start going south quickly.
Heck, my best friend's little sister is another BPD example. She's cut off her entire family, all our friends growing up, etc. Yet her and I are still cool because I communicate with her a different way and always tell her that I'm there for her, I understand why she's upset with others, etc.
It really makes all the difference in the world and you never get to the meltdown stage.
