She is exploring. All WA's do it. Those of us left behind explore, I think its healthy to explore to a point. I imagine she will be healthier for the experience. Life is about experiences and if we are wise we learn from those experiences. If she does come back she will have experienced the things about you that she took for granted, and will really appreciate them. Some of it is just a superficial distraction, but all in all I would like to believe that life changes make us better, stronger and wiser. I know the changes in my life have made me a better person.
