gunny, 15 minutes isn't really a whole lot of time to make any kind of assessment. No question she's on her own path on your on your path. Frankly, I suspect I like your path a whole lot more.
I would say, however, there's a good chance she may have felt lost in being an avid runner with you, and now she's trying the exact opposite, kind of in rebellion.
I guess you have to ask yourself if the path she's on right now is even attractive to you. I'm not sure the answer would make a difference other than you being satisfied with the path you're on.
I think you've been doing a lot of good things for yourself. There's always the possibility that will be attractive to your W. If not, it will be attractive to someone else.
There is one unknown in this equation, too, and that is what were her thoughts when she saw you? You may never know. It may have had an impact or it may not have.
Keep up the good work, my friend. Enjoy your time with your dog!
