Ok, at this point I really have had enough of Bethesda and their glitchy games. Looking online, getting married in Skyrim seems to have a multitude of problems, and now it's just cost me about a day's worth of playing.
It starts with me talking to Marathal, getting the marriage option, but then nothing happening when he askes me if I understand how marriage works. I pick one of the answers, and it just leaves the dialogue. Being a semi-intelligent sort, I figured out to just talk to my follower anyway (in this case Jenassa), and get her to agree, we set up the ceremony, etc. However, after waiting for a day and walking back into the temple, I walk up to the altar where Jenassa and Marathal are waiting, and when I get there, nothing happens. We just all stand there, I can't move except to look around, no one talks. I tried reloading the autosave from entering the temple, and that got him to raise his arms and move his lips, but no words, nothing. I try waiting, nothing. Of course, waitning overrides my autosaves, so I the only way out was to use my last manual save, which I don't do all that often and cost me about a day's worth of playing.
It's a shame, because I'd have to say 2 of my top 3 game series were Elder Scrolls and Fallout, but now I've just had my fill of Bethesda and their rushed-to-market games loaded with glitches. I don't know why they constantly seem to have to rush their games through production, and why they can't just meet their deadlines so they can release a reasonably glitch-free game, but at this point I truly believe Skyrim will be the last Bethesda game I ever buy.
