It's dangerous to keep bonds open, even those between parent and child, or husband and wife. Less so, now, maybe. But though Morgoth is defeated, Sauron is at large, fled from Eonwe rather than taken into custody.

(The Valar, as ever, remain careless with their own kin, and hers will doubtless be the ones to pay the price)

The Silmarils, too, are gone, and with them the last of her cousins, and Beleriand is crumbled beneath the waves.

The world has changed, and is changing, but some things remain the same.

It's not unusual for elven partners to walk apart, she knows it well. Even her own parents spent at times several years apart after their children were old enough to fend for themselves. But here, in Middle-earth, she worries, as no one in blessed Valinor ever had reason to. She has had no word past the time he promised, and she dare not open the bond, not when she has no idea what she might find on the other end. What use are her vaunted strength of mind now, when it is too dangerous to use? Even her Mirror is not helpful, clouded by her own fears.

Surely, at least, she would know if he died.

(But there are worse things than death, in Arda Marred. They learnt THAT lesson in the First Age)

Is he captured? Is he wounded?

Surely, she would know if he died.

All she can do right now is smile for their daughter, smile for their people, and watch the borders, anxiously.
