Is my husband dead if i don't find him in Skyrim?

In Skyrim, if your husband is missing, it may not necessarily mean he is dead. Characters can become unresponsive or get stuck in the game world due to glitches. You can check the last location where you saw him, or try waiting for a while to see if he returns. If he is truly gone, you might need to consider remarrying, as some quests or events can lead to a spouse being lost permanently.
