Any way to change this via the Creation Kit? Odd request I know but I loved it in Dragon Age: Origins! =D

I knew this would come around soon. Quick look: I would venture into the marriage questline and see if it can be edited to loop back to the beginning so that after you marry, if you wear the amulet again you can approach another interest and redo the quest with them while maintaining your current relationship. Whether there are variable constraints on number of spouses and where they may be I'm not sure. still searching for some things myself.

Well I can do that by changing the stage via Console to take me back to the quest, but it'll only let me remarry if I don't have a wife already. I tried before CK even came out =(

EDIT: But I'll see what I can figure out about the marriage quest line.
