Hi Pook075 ,
Indeed, the fact that you have good memories make all of the difference. I don't have any good memories of past wives. We didn't ever have any good vacations together, we didn't have any favourite restaurant and we didn't ever do any hobbies together. The good memories I have are about my kids only.
There were a few vacations that I took with my first wife before having kids, but all of them were painful and very restricted because of her jealousy, her self-image problems, and her OCD problems. After having kids, having vacations became impossible. First wife was overly stressed and hostile all the time. The second wife was always pathologically jealous about my stepkids. Third wife is cool but has specific phobias that make it impossible for us to travel.
Hopefully, her BPD treatment will address her anxiety disorders as well. It's obvious to me that she is unconsciously attached to traumatic memories because of her need to feel in an emergency situation, so that her EOS is activated. Specific phobias are easy to treat, but she keeps sabotaging the treatment. Once her EOS is working, she will finally be ready to get cured and then whatever treatment she does will work (such as exposure treatment, hypnotherapy, EMDR, or treatments that use psychedelic drugs).
My experiences are basically impossible according to this site, and it's because BPDs explode, we explode back, and it's scorched earth from there on out. I fortunately was able to take a different path though and I'm very thankful for it.
We explode back? No, I don't do that. I have never messed up things because of my temper. My self-control is extreme, and I have the temperament of a calculator.

At work, in situations of pressure, people have said that the world was ending while I was calm and poundering. But that's because it takes a lot more to get me stressed. And even when stressed I can act peacefully.
It's true that I couldn't express love for my ex-wives since I didn't actually love them (not anymore, at least). But even if I did love them, I'm sure that courts would still be needed to dispute the financial part and parenting time. For instance, with my second ex I have almost always been able to negotiate 50% parenting time, sometimes more, but in courts she always denies it happens and requests the minimum for me, because she wants to have the control and to secure the pension value since she does not quite work.
A BPDs biggest fear is abandonment or being rejected, so you inadvertently made their worst fears come true. And in retaliation, it went about as badly as it could have. That's 99.9% of the stories here so it's not like you did anything wrong.
Well, that's true. But how can I end a relationship without triggering her abandonment fears? I don't think this is possible. Therefore, in situations like mine in which their abandonment fears were triggered, I think the best option is to plan everything in advance and use courts for everything early, before they use courts on you. But unfortunately for someone laid-back like me, who is never angry, it's hard to do that.
But at the same time here, there's definitely a lesson for you on marriage #3. It doesn't have to be scorched Earth and a massive legal battle.
Unfortunately, I disagree. Your ex is not evil, but my ex's are, in a way. It did have to be a massive legal battle, and 80% of the court disputes were started by them. People like them do not accept fair agreements, ever.
With my current wife, however, no legal battle will be needed. Even because we won't separate. But if we did divorce, I know that she would want the best for me. That's why I love her, for the person that she is deep inside.
.. there's a theme in the Bible indicating that the past is dead. I've held onto that because we can't change the past, we can't fix our mistakes, and focusing on it can only bring hardship.
Well, that's true, but the only way I can be safe now is to keep my memories from the recent past active. Otherwise, I'll just end up in the same situation again.
When the BPDs in my life bring up the past, I'll speak very briefly on it and apologize that I couldn't meet their needs better back then. I'll say that I'm not perfect and I've made mistakes, and that I try to learn and grow from those mistakes. But then I'm finished talking about it because I'm not going to dwell on it or try to relive it. We literally can't do anything about it, so why focus on it at all? Just apologize and move on.
Your wife might still bring up the past often, but you have to see above that and steer away from it. That mindset is so toxic for so many reasons and it brings back trauma. BPDs are remembering their feelings of the bad stuff, not necessarily what happened or who said what. So apologize for hurting their feelings and let it rest.
I agree that stating we can't change the past and moving on is good. Also, asking them, "Before I answer, please tell me, what is the purpose of this conversation?" is an excellent approach, because they might not have an answer. However, your suggestion to apologize is usually not an option for me.
If she says that I hurt her feelings, I can certainly apologize for that. But if she says that I didn't buy sufficient food or didn't give her enough freedom, this is a distorted view, and apologizing for that could possibly reinforce the distortion.
For instance, she brought up that I was too controlling about the amount of time our boy sees screens. She accuses me of taking away her rights to use screens with her son. Her narrative is not true, because I always tried to talk it out, but she made a war out of it. So I'm afraid that apologizing to that would feed into her narrative?
And there is no point in this discussion because she is actually aware that screens have made him laten his speech. She does not even use screens in her mom's house.
Do you really think we should apologize for everything, even for the distorted narratives?
