Went out to brunch with LTR. After brunch we met a mutual friend (woman2) and all got drinks together. During drinks, my LTR joked about how many guys she has dated prior to me. I act amused, and joked with her by saying "and there will be many more after me". Note that I was actually a little annoyed.

Woman2 laughed and played along, seeing the amused mastery she became interested and did the usual light flirtation of a friend, but nothing beyond that. Literally during this, my LTR kept quietely whispering to me "wait are you mad at me?" I maintain frame, A+A "Oh yeah, furious." with a smirk/eye roll.

After drinks we walk out to the trains and while I'm slightly annoyed LTR brought up her past boyfriends I don't really give a shit. It seemed somewhat disrespectful in front of another friend but she was worried and holding on to me. She asked me to take a different train with her that was further away and slightly more inconvenient and I said no, I'm going to take this one. I kissed her on the forehead and said I'd talk to her tonight.

Since my phone was dead, I when I booted it up at home she had gone nuclear. "You wonder why I'm worried about our relationship? You totally ditched me!" to which I replied "Ditched?" and that's it. Been a few hours,no response.

Is this one of those instances where I took dread too far? It was actually pretty accidental if I did - but I would like a quick game/frame check here if possible.

TL;DR: Girl brought up exes in front of friends. I applied some (what I considered) light dread, she has gotten super pissed. What are my next steps? Do i maintain frame, or did I overdo the dread and do a little more comforting?
