Skyrim Marrage Help?

[Firefly Flame]

I haven't done it myself, but I've read that if you miss the ceremony, you have to apologize to your intended and convince them to try again. Not sure what that means, though. Maybe you have to wait and let Ysolda return to Whiterun, cool off for a few days, and then visit her wearing your amulet of Mara and see if there's an option to talk about it, ask again, or do another quest to regain her favor. Or just marry someone else.
