She's growing up. Remember, she had felt 'controlled' with you. Now she knows she can be herself, have her own independence as a person without being dependent on you for her support or her emotions. Now she is sharing her _big_ life experiences as a grown up does with another grown up. With you.
This is exciting to watch. This 'independent but also a partner' was that exact same thing my W had to resolve before she understood that she COULD be married to me and still be her own person.
Very exciting to see this change.
Especially since she could be sharing this experience with anybody. But she chooses to share it with you.
