I don't know if you can easily see this, a lot of conflicting things in the things that you say and do.
This is not fault finding - its intended to be fix focusing. If you can see yourself in this, you can then start to move out of it.
I don't know if you've studied the 4 horsemen (Gottman) or the Karpman Triangle - we have articles for both here (use the Google box below the moderators names) - but there are learned behaviors that we can fall into in difficult relationships that are self defeating.
We want to shed these. To do that, we have to see them and we have to be committed to end them. They become second nature - a habit to break.
4 Horsemen Gottman shows four stage of communication breakdown that occur when a relationship fails. One point he makes is that when you reach stage 4, it is totally self defeating. In stage 4 we become conditioned to failure, and so we become overly defensive and make often matters worse (or at least not better).
I think you have the hallmarks of communicating in the stage 4 style. It most likely started months before you left. The way you left was very stage 4. Yesterday was stage 4.
It likely a byproduct of the relationship, but it shapes (distorts) how we see things and it will take some focus to shed it.
For example, you really desire that she reach out - even if its just to be cordial - but you are communicating back to her in what can only be perceived as angry, and bitter (the way you left, the NC, the texts yesterday). You even call it "fighting back".
We could argue that there is only a 50% chance (or 20%) that she will become cordial with you (she did with her other exs) - but if you're are putting up an angry and bitter front - its 0% chance.
No matter how justified - moving out the way that you did, and responding the way you have is not consistent with leaving the door open for fence mending. I think it will feel better to you if you can balance the hopes and the fears and rise out of stage 4. It takes a lot of mental energy to be out of balance like this.
I'm not suggesting you reach out (or not reach out), I am saying that it will help to get out of stage 4 and it will help to align what you want with how you act. It doesn't make sense to want her to open up while you are shutting her down. Pick one.
Karpmen triangleThe other learned behavior is a Karpmen triangle victim. We can get into a mindset that we are helpless and take on a not-so-great way of dealing with things. We gravitate to what Karpman calls the ulterior game. Fjedstadt explains this well in her book,
Stop CareTaking the Borderline or Narcissist. We have a good article here too.
If you look at how things escalated yesterday, step by step (post by post) its follows a classic a Karpman pattern and it ends here:
From KarpmanThe victim sincerely feels victimized, oppressed, helpless, hopeless, powerless, and seems unable to make decisions, solve problems, take pleasure in... .From you (yesterday)When we fight a bully on their own turf they have the advantage, the know the lay of the land and where to hide and where to run and where to FIND YOU when you hide. Texting and emails and phone calls and letters that are nasty, hurtful and other unspeakable things. My ex wanted to fight me on her turf today. No one is better at manipulating me and devaluing me than she is. WHY? because those things are HER TURF, and not mine. She'll win every time.
I know you love her. I know that this was a huge loss. I know it seems senseless and irrational. I know it really did a number on you.
