Have you ever proposed to an NPC somewhere special in Skyrim?
For instance, I have married Onmund on 3 characters.
One time, I proposed to him on top of the Solitude Lighthouse at Midnight.
Another, I proposed at the Burning of King Olaf.
On my most recent save, I proposed NW of Riften, in the hotsprings.
Anyone else do this, or am I just weird?
