Ok so i go to get married to that chick in shor's stone, and i go to the chapel and start the wedding. Then i go outside and wait till the next day, then go into the chapel to attend my wedding.
I get in to see the wedding about to start with all my guests, except one of my guests is a bandit that attacks the wedding and gives me a "failed quest" on the attend my wedding. Once the entire army of my guests kill the bandit, i go to talk to my would be wife and she tells me to get lost cus i broke her heart.

What the hell is this?
I reloaded the game before i asked her to get married, tried again and the same exact thing happened.
Then the next time when i started the wedding, instead of leaving i waited in the chapel. Once it was the next day, every one of my guests pour in all at once, one of the guests being the bandit, and instantly i get a failed quest thing again.

Except this time when i talk to her again im able to say it was a mistake lets try our wedding again. She says ok and i go talk to the pastor guy again. The pastor guy tells me to get out of his face because i mocked mara somehow. Then i leave, wait an hour and come back and talk to him and he lets me start the wedding over again.

Ok so that done i walk out the chapel past the dead bandit's body. Once im outside i go to the bar get a room and sleep til the next day. Then i come back and enter the chapel to find all my guests there AND ANOTHER BANDIT who again ruins my wedding. So i kill him and now theres 2 dead bandits next to eachother and my wife tells me to get out of her face.

Seriously this is some [censored] glitch. Does anyone know how to fix this at all? Im on the Ps3 version and i have update 1.07.

He just wanted to congratulate you on your accomplishment. Why did everyone have to attack him?

You have too many violent guests. For shame.

Maybe they were jealous ex-boyfriends, and everyone else blames you for a death at the wedding

Ha, best Skyrim wedding ever

So much more interesting than if it went to plan !

I once travled to the college of winterhold and a draugr started to attack me. I don't know where he came from but that's the first time I ran into a draugr outside a dungeon.

Was one of the bandits named Bill by any chance?

Looks like your girlfriend had many "bad" friends...

It's happened to me a quite a lot, actually. That's a Conjuration glitch. Sometimes you raise undead and they get lost or for some reason the game just derped and decided to give them back to you at the most random moments.

One time I fast travel to High hrothgar and a bunch of bandits, spiders, and what I thought was a werewolf, spawn but they immediately fell off the mountain

This is what I'm thinking too.

Another possibility, it wasn't meant to be. This was the divines way of keeping you from making a mistake.
