Maybe one-on-one attention...take her away for the day...to the forest or a park in a neighboring city. Walk and sit and walk more. Look for fae gardens (oops, that was projecting a little too much me

).
If weather wont let y'all be outside, maybe a museum or a window shopping spree. A bookstore or music store where y'all can share favorites - new & old.
Sit & have coffee (or whatever) and ask her all kinds of open-ended questions about her - what she loves, what makes her happy, what would she do with $10 million?
People watch & make up stories about those people y'all find interesting. Touch her often, softly, quietly. Or loudly....
i should stop now.
Have fun!
