When you protect her, don't stifle her independence. She can't always see when something harmful is happening.
Take her to an amusement park, take a walk through a flower garden, climb a rock wall, go on a white water rafting adventure, or go to an escape room.
If you meet all these and more, then I'm so excited and happy for her, but please don't hog her because I need her too! I need to spend time with her too, but trust that most of our time will be spent talking about you.
Whether those are good or bad things, that depends on you.
But surprises don't have to be some grand scheme or some expensive trip.
It can be bringing her her favorite food to work or buying her that new book she's been talking about. It may not end, but it will die and no one wants to be in a dead relationship.
