I've read that many annulments come about during the course of folks converting or being received into full communion with the Catholic Church. And many of these folks bring a whole set of luggage with them. I've known converts with two, three failed marriages prior to conversion. Since these folks are formally converting, it seems reasonable that many of them have learned something or have repented of something that makes it possible that they may attempt marriage again.
