My ex (who is poly) told their newest partner a lot of personal info about myself to them without asking. A lot of insecurities, traumas and history. Their new partner ended up throwing this all in my face in an altercation.

My ex has since apologized for doing this, explaining it was really shitty and immature and they never meant to give me more trauma. They said their apology won’t fix the damage that’s been done and I agreed.

We’ve since started a mutual no contact time and yet I find myself struggling with what happened. I never asked exactly why they did it. It’s affecting my sleep now as I’m having nightmares about it.

I’m considering breaking no contact to ask them why they did what they did. But I also realize at the end of the day it might not even change anything and what is done is done.

Any and all advice or suggestions are more than welcome. Thanks in advance.
