And without the Console since I'm on the Xbox 360. I've read that it was a bug, and now it's saying it was never possible to marry her at all - That most likely it was an error on the author's part for putting it in the guide. Too many mixed conclusions and I don't know which one is true. Post patch 1.2 you're still not able to marry her.

Anyone have any idea?

your supposed to be able to but it never gives you the option pc players can with console commands i think

She is my wife, and yes. You are able to get the request to marriage in conversation, if u use console command. Shame, but i wanted her so i done it. I cheated the bug
