It's great to have good conversations with her and it's nice that a touchy subject like 401K splits/money, etc, doesn't set off anything bad. My advice is to not analyze a conversation other that to think to yourself whether it went well or poorly, but don't assign any particular significance to it.
Since you are going to see her later anyway, perhaps you could consider my suggestion on your thread. My biggest recommendation is PATIENCE. Don't wait for or anticipate anything abrupt happening. I sucked at that myself and only learned it by giving up completely because then I felt it didn't matter if the convo went south. Don't get any expectations about her positive or negative.
