I haven't heard anything like this in a while and although I appreciated it and said "that is sweet, thank you" I have been mind reading and analyzing this to see if its a good sign about her noticing I'm becoming a better man or if I should just take it at face value and maybe it means nothing as far as our relationship goes. And then I am fearful that she thinks us being seperated is working out better than when she was living here.
I think you take this as a small positive. Hang on to and collect the small positives as indicator you're on the right track. As 2tp suggested, putting these in a solution journal if you have one might not be a bad idea. It's all baby steps.
