It's my first time posting and I'm using my phone so I apologize if anything is weird. Also, English isn't my first language.

I (18F) recently broke up with my ex (25F) because it was a very toxic relationship. We were together for more than 3 years but I finally had enough so I decided to end things. It has been half a year ever since we broke up and i started dating someone else.

Unfortunately, I said something so personal regarding my childhood trauma to my ex and she just told that to the person that im dating now. I confronted my ex and she said that she was just telling my current partner to let them know about it, "out of concern" for me. I'm still crying about it since i confided in her because I trusted her, but for me it wasn't her story to tell whenever she wants to. My current partner just said that they already know about it (even though they didn't) and thanked my ex for letting them know. They also didn't ask any further details about it.

I'm someone who hates confrontation and will never argue with anyone when there's other people. I keep whatever issue i have with someone between us and will act civil in public no matter what. My ex knows that and now she's bringing our friends into 'our current beef' when the beef is just me blocking her and telling her to leave us alone. My ex would even visit my house with some of our friends since I won't even open the door when it's just her. I told our friends to just let us deal with it since it's our problem but they kept insisting that i should at least unblock my ex so we could speak but i refused. I honestly got tired and now just blocked everyone, even those who didn't say anything. I blocked everyone in our circle. I guess on my end i don't think i did anything wrong, but i still need an outside perspective. Thank you.
