As difficult as it is, try to be positive when you see her. I'm having problems GAL and detaching, so I know how difficult it can be. My H dropped the D bomb while I daughter was up north with my family. I flat out refused to do anything while she was gone. I didn't want her to think something bad would happen everytime she went away.
