You can't know what she was thinking. It could be that she feels guilty, so she's asking questions. It could be that she thought it was awkward to text after so long and then make it just about her stuff. It could be that she's confused and misses you. You don't know.
So, take it as a positive interaction, but don't develop any expectations from that basis. I've spent entirely too much time in my head over the past several months wondering what my H was thinking. Really, it was just a colossal waste of time.
