Why you should not be late to your wedding...

I was playing Skyrim last night (much too late), and I discovered there is a certain amulet your character can wear and people will start expressing a romantic interest in him/her. To cut a long story short my character basically asked her long time, favourite companion at arms to marry her. But due to a misunderstanding on my part (yeah, yeah that's everyone's excuse I'm sure) I was late to the temple for the wedding, and thus failed the 'attend your wedding ceremony' quest. Now not only is my character not married, but her friend has disappeared and I don't know if she is coming back! And, of course, I don't have an appropriate save point to go back and try again.

I am far more annoyed with this than I ought to be.
