Search Results: how to blow her away

To briefly summarize, I met this girl at work 6 years ago, and we dated for about 7 months before she broke us up for two years because she was mormon and I wasn't. We got back together and we dated for almost two years, with the understanding I'd try her church, and if I didn't like it she wouldn't pressure me and it wouldn't change.
But everything changed because she went on a mission, she broke us up, and spent half the mission trying to convert me, and then stopped talking to me.
She blew me off when she came home and lied to me and accused me of things I didn't do in the relationship.

It's been a year, I have a girlfriend, and my ex is now married. But we had jury duty together this week, and it was strange. Once it concluded, she came up to me and asked how I was doing. I responded, but I didn't ask how she was doing. She asked if I was gonna ask her and I told her I didn't care. She got upset and said if I had loved her I would care about her happiness now.
I told her I stopped caring, I thought the world of her and she betrayed me and spat in my face. I had once loved her, but I didn't feel for her, and her words were hallow because her actions left me feeling her 'love' was just words and part of her manipulation of me.
She said she did, that she cared about my happiness and that she's looked at my social media to see how I'm doing. I told her I was happy to know so I could block her. I told her I'd never forgive her for what she did, but I moved on and don't care about her. As I walked away, she started to cry but I didn't stop and kept walking.

Was I too harsh?
