It is a misunderstanding. There is a concept of “bashert” meaning a person you are destined to marry but that doesn’t mean you can only be successfully married to that person for two distinct reasons:
1. You have bechira and can make a marriage work with many people. Moreover your destiny may be to have a difficult marriage with the person you were meant to be with.
2. A person can break their fate and get a spouse that they deserve (better or worse than they destined spouse). ???
