Ahh, very interesting indeed. My advice is to focus on the positives from last night and try not to read into anything, but you didn't need me to tell you that. I think yes, this is a change in something...the question is what. Right now is the perfect time to show her that you have made changes in yourself....she will likely test those so stay alert. You have seen some positive signs and I hope they continue for you.
