Friend and my ex

Would you be mad at your friend for going around telling people your ex reached out to them sexually?

Someone you just broke up with a few months ago?

She told me about it but refused to block him bc they go way back and he had never done this before but she wanted to “put him” in his place.

I got pissed off bc how are you going to tell me about this and still want to be friends with him? I told her she could keep him unblocked but I couldn’t be friends with her after that. Plus she also made it about herself be saying later “I honestly don’t know if my bf would want me being friends with him so it’s 50/50” like what?? Why are u making it about you? I’ve been your friends for YEARS and you can’t cut off my ex who she never talks to besides needing a cart for her pen. (That’s what she means when they go way back)

She ended up telling our friend group and I got a bunch of msgs from my friends saying shit about him, how they wouldn’t know what to do if I were me, blah blah. I have been doing nothing but focusing on myself since he and I broke up. I stopped mentioning my break up to them about three weeks after he and I broke up. And I just feel like by telling everyone she created unnecessary drama? She says it’s her choice and her story to tell about what he did to her (reaching out to her sexually). But I wish she would’ve kept it between us. Now it’s a whole thing in our friend group I just wanted it to stay peaceful and move on cause that’s what I’ve been trying to do.
