I posted the following in a 'marriage glitch thread' yesterday. But as there seems to be lots of similar threads I've repeated it here.

This worked for me:

1. Drag the dead body to the cellar.
2,. Wait 24 hours
3. Tell the priest you're really sorry (he tells you to see your betrothed)
4. Tell your bethrothed you're really.. really sorry....
5. 24 hours later..... get married........ (I took off the 'love' amulet before ceremnony it might make a difference, not sure)

However, due to the second wedding glitch...

6. Save during ceremony before 'rings' mentioned (you may have to retry)
7. If bride walks away whille priest is still talking press B until your free...
8. If you can catch up with her... arrange where to live... if successful
9. Meet her at 'home'!

It worked for me twice (2 different brides).

Good luck and congratulations on your wedding!

Feedback would be good
