I've played this game for awhile, I'm no noobie. My characters have done it all, including marriage. But now my current character cannot get married. I go through all the motions - get the amulet, ask and am accepted, shcedule a wedding - but when it comes time for the wedding I get a "Failed" message and my bride and all the guests act like I did something terrible. I've tried all sorts of ways to do this, and times of the day to show up, including juat staying in the temple for the whole night before, but I get the same thing every time.

Is there anything I can do? This is obviously a glitch, unless I've forgotten something (which I very much doubt). Any ideas?

Hm. I usually wait outside the temple until wedding time.
I havent gotten married for a while though... so I dont know if I have the same problem as you, but just dont know it yet.
