That's a win. You may have felt all those emotions, and you can't control them. But you CAN control your actions and you did. Rest assured, she felt them 100 fold - she's a woman. It will drive her up a wall that she didn't elicit a word out of you...not that that matters (who cares what she's thinking), but it helps keep your own emotions in perspective and give you a sense of the progress you're making.
My goal, besides obviously keeping myself in a positive state and achieving growth, is avoiding giving an ex any material to flame me with down the road. Sure, when emotions are high, she'll be sad/pissed/vengeful. But after a year or two, feelings go away, and I don't need a reputation of someone who started (or continued) unnecessary drama. There's only one girl I couldn't achieve that with, but she was/is a narcissist, possibly BPD and definitely just rotten so I don't care, lol. (And she still stalks me on LinkedIn almost every other week.)
