You are really moving forward, T. It must make your life more peaceful.
When/if you end up in one of those convos again, you could cut it off politely. Not that you wouldn't be willing to discuss but at a time and place that was more acceptable for you.
It's really hard to keep a convo like that on topic, so any time she veers off, bring her back to the topic and let her know everything else is off limits.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
