It happened to a sim once, not my doing either. I think it was before NL, he was family aspiration made in CAS, she a romance townie. He asked her to move in, then were engaged, no problem there. Then I made this whole production for the wedding, music, food, cake, the works. She bolted at the altar. Can't remember about ex's at the party though.
The problem was she had to come back home, cause that's where she lived... There was hell to pay, nobody wanted to talk to her (other sims in the lot were the teenage son and the father of her fiance, so you can imagine...) I don't think I've ever had it happen again.
