Ignore it! you could mind read until the cows come home and never understand. Just remember that was we want to do is not always what our friends and families think we SHOULD we do! And what she may think of as negatives, you or your W may think of as positives.
I've lost one of my friends that I was very close to around the time of being a walk away I don't think she knows what to make of me....and that's okay. I'm not explaining myself to anyone!
It sounds like the two of you had some very positive conversations. Keep it happy and fun, so that when she thinks of you it isn't with guilt or bad memories but with excitement!
