OK, so I ended up getting married to Ysolda. Yay? Well anyway she started to get on my nerves with her 'Returning from a great adventure I bet,' or something like that. Anyway, I.... Well... Kind of killed her. That and I also wanted to be with this other person just because he was a miner.
I have learned, it doesn't seem possible that I can get married again. I even went to the Temple of Mara in Riften and I wasn't able to talk about marriage or anything again.
Does anyone know if you can get married?
(This mainly started because I wanted to see if adultry was possible in the game. I ended up reading a letter that talked about suspicions of adultry and it game me the idea.)
