Mr Bond is giving you some very good advice and from what i read you are getting good signals from her.
I know you probably want more, you want the security of knowing that she is back to her old self.
It may happen but you really need to take it slow dude.
Change is a part of life.... how we deal with it says a lot about us. Can you go with the flow, remain positive, be a light for her...while she changes and works through whatever it is she is working through? You cannot control how she feels/reacts to you but you can control you.
So plan a trip just you and her... has she wanted to do anything lately? Does she have a hobby that she stopped? Think what could you do to make you and her feel good?
