Ever since the patch, Ysolda isn't killable. I want to divorce her. I finished "A Night to Remember" quest, but she still isn't killable. Please help. How do I get rid of her.

(I play on Xbox 360)

That's a strange question... Which platform are you on?

360

I would take her out hunting. go to a giant camp and let the giant's beat her up... It's how aela died and she wasn't killable

If you want to divorce her, simply tell her you want to move to her house. Then you just don't move there with her.

If you want to kill her to re-marry, forget it. There's no re-marrying in Skyrim.

Aurora is right. If you're killing her because you got the hots for someone else, you're going to have to keep the affair going and just hope Ysolda never catches on. Skyrim portrayed marriage kind of how it was meant to be. You know, the whole one wife/husband for life thing.
