I'm sorry you lost such an important relationship.

I think maybe doing some reading about bipolar might help you understand it better. An unquiet mind by Kay Redfiled Jamison is a good start. There are lots of others. But reflecting on psychosis is not really happening for at least me in the way you are hoping. She may come out of it and go back to feeling the way she did before the mania and not feel that what she has said through the mania was meaningful or not what she meant. She may not remember any of it. She may only kind of remember it, like a hazy effect. It isn't something I've ever come out of wanting to analyze nor have I ever been encouraged to do that; it's usually been "that's over, now let's put your life back together". Because I can spend as much time as I want thinking about the people I ran from in fear yesterday but that doesn't really change anything about how afraid of them I was at the time. The thoughts are irrational and therefore thinking about them rationally won't help fix them. Does that make sense? I feel like I'm walking a tightrope trying to explain this and I apologize for that; I know what I mean but I don't want to put words in anyone else's mouth.
